Ruanda-Urundi: AD 1887-1914
 The highlands of Rwanda and Burundi, east of Lake  Kivu, are the last part of Africa to be reached by Europeans in the colonial  expansion of the late 19th century. Before that time local tradition tells of  many centuries during which the Tutsi, a tall cattle-rearing people probably  from the upper reaches of the Nile, infiltrate the area and win dominance over  the Hutu, already in residence and living by agriculture. When  first described by Europeans - and in particular by Speke,  who encounters them east of Rwanda on his exploration to Lake Victoria - it is  assumed that the distinction between Tutsi and Hutu is entirely racial. But this  simple classification is blurred by intermarriage and by the custom of allowing  people to become honorary members of the other group.A more valid  description of the Tutsi-Hutu divide is by class and occupation. The Tutsi are  the upper class and are mostly herdsmen. The Hutu are the lower class and for  the most part live by farming.
  
The first European to enter Rwanda is a  German, Count von Götzen, who visits the court of Rwabugiri in 1894. The next  year the king dies. With Rwanda in turmoil over the succession, the Germans move   in 1897, from Tanzania, to claim the region for the Kaiser. At the same time  they claim Burundi, a separate kingdom to the south. The entire area is treated  as one colony, to be known as Ruanda-Urundi. German rule in this most  inaccessible of colonies is indirect, achieved mainly by placing agents at the  courts of the various local rulers. So the German influence is not yet extensive  when the region is taken abruptly from their hands after the outbreak of the  European war in 1914. 
 
A Belgian  colony: AD 1914-1962
When Germany invades Belgium, at the start of World War I, the  Belgians retaliate in a smaller way in central Africa. Belgian troops move east  from the Belgian Congo to occupy (in 1916) Ruanda-Urundi. After the war the  League of Nations confirms the existing state of affairs, granting Belgium in  1924 a mandate to administer the colony.From 1925 Ruanda-Urundi is  linked with the neighbouring Belgian  Congo, but colonial rule takes a very different form in the two territories.  The administration of the Congo is centred in Brussels, but in Ruanda-Urundi it  is left in the hands of the Tutsi aristocracy. Indeed the Belgians, observing  the distinction between Tutsi and Hutu, make it the very basis of their colonial  system. 
  
The Hutu  are subject to the forced labour which disfigures many European colonies in  Africa, but here it is the Tutsi who supervise them at their tasks. From 1933  everyone in Ruanda-Urundi is issued with a racial identity card, defining them  as Hutu (85%) or Tutsi (14%). The remaining 1% are the Twa, the remnants of the  original Pygmies  indigenous in this area.This Belgian attitude, setting in stone the  distinction between the two groups and favouring one of them, prepares the  ground for future violence (in earlier times racially based massacres have never  occurred between Hutu and Tutsi). The predictable occasion for its outbreak is  the rush towards independence in the late 1950s.
  
The  problem is more immediately evident in Ruanda than in Urundi. In 1957 Hutu  leaders in Ruanda publish a 
Hutu Manifesto, preparing their supporters  for a future political conflict to be conducted entirely on ethnic lines. In  1959 the first outbreak of violence is sparked off when a group of Tutsi  political activists in Gitirama beat up a Hutu rival, Dominique Mbonyumutwa.The resulting nationwide campaign of Hutu  violence against Tutsis becomes known as 'the wind of destruction'. Over the  coming months many Tutsis flee from Ruanda, including the 25-year-old hereditary  ruler, the Mwami.
Independence:  from AD 1962
The two parts of Ruanda-Urundi become independent in July 1962.  There is pressure from the UN to federate as a single nation, but both opt to go  their separate ways. Ruanda, in which ethnic violence has continued during 1960  and 1961, becomes a republic. The spelling of the name is changed  to Rwanda.Urundi, by contrast, becomes independent as a constitutional  monarchy, but again with a change of name, to Burundi.
  
 In  December 1963 several hundred Tutsi guerrillas enter southern Rwanda from  Burundi. They advance to within twelve miles of the capital, Kigali, before they  are eliminated by the Rwandan army. This event prompts the government to declare  a state of emergency, emphasizing the need to 'clear the bush' of subversive  elements.Within days some 14,000 Tutsis are massacred in the southern  province of Gikongoro, in a coordinated campaign described by Bertrand Russell  as 'the most horrible and systematic massacre' since the Holocaust.
 
In the interim there is a coup within the Hutu regime. In 1973  Kayibanda is removed from power by a group of army officers who replace him with  a major general, Juvénal Habyarimana. Habyarimana remains in power for  twenty-one years, running a conventional self-serving military dictatorship  (with enthusiastic support from several western countries, in particular  France). But his Hutu ethnic policy creates an increasing problem on Rwanda's  frontiers. Over the borders there are a vast number of mainly Tutsi refugees. As  time passes they are increasingly unwelcome in their host countries. Efforts are  made to send them home. But Rwanda rejects them.
  
In 1986 Habyarimana states as a matter of  policy that there will be no right of return for Rwandan refugees. In the  following year Rwandan exiles form the group which soon transforms the situation  - the RPF or Rwandan Patriotic Front, committed to armed struggle against  Habyarimana's regime.
The nucleus of the RPF is Tutsi officers serving in  the Ugandan army. On a prearranged date, 1 October 1990, they desert from the  army with their equipment and move south over the border into Rwanda. It is a  minor invasion which eventually, against all the odds, puts an end to  Habyarimana's regime. But it also provokes one of the century's most appalling  acts of genocide. 
 
The prelude to  genocide: AD 1990-1994
President Habyarimina is able to repel the initial RPF  invasion of northeastern Rwanda, in October 1990, largely thanks to French  paratroops sent for the purpose by President Mitterand. But the event provides  the pretext for a new wave of Tutsi persecution within Rwanda. 
The  country's most fervently racist newspaper publishes in December the Hutu Ten  Commandments. This is a litany of hatred, attributing dishonesty and treachery  not only to all Tutsis but also to any Hutu who befriends them. The eighth  commandment, quoted at the time more often than any other, is: 'Hutus must stop  having mercy on the Tutsis.' In 1991 a name is coined for this new level of  ethnic triumphalism - Hutu Power.
 
To  ensure the effectiveness of Hutu Power, Habiyarimina's government begins to  recruit Hutu youth militias. These become known as the Interahamwe, meaning  'those who attack together'. In public these violent young men roar around on  motorbikes, like any gang of hooligangs, and hold drunken rallies under  portraits of President Habiyarimina. In private they gather together to perfect  the skills of wielding machetes, setting fire to houses, and drawing up lists of  local Tutsis and Hutu sympathizers.
In this mood ethnic violence  increases steadily, and is often ratchetted up a sudden notch - as when, in  March 1992, Radio Rwanda spreads a deliberately false rumour that a Tutsi plot  to massacre Hutus has been discovered.
  
By 1992  President Habyarimana is himself beginning to disappoint his extremist  supporters. Having failed to suppress the guerrillas of the RPF, and under  international pressure to come to terms with them, he begins to negotiate. The  news that he has agreed a ceasefire, in August 1992, provokes a new wave of  attacks on Tutsis. Over the next year the peace process continues, alienating  the president ever further from the thugs of Hutu Power.In August 1993,  after talks at Arusha in Tanzania, Habyarimana signs a peace treaty with the  RPF, officially bringing the war to an end. But the terms of the treaty go much  further than that.
 
In what becomes known as the Arusha Accords,  Habiyarimana accepts the right of return for all Rwanda's refugees, the merging  of the RPF with the national army, and a transitional period leading up to  elections and a democratic government. During this period power will reside with  a provisional government in which, most startling of all, the RPF will be  represented. And UN forces will be invited into Rwanda to secure this  process.These concessions seem outrageous to the Interahamwe and their  political masters. On 6 April 1994 a rocket, almost certainly fired by Hutu  extremists, brings down a plane. In it are two presidents - Habyarimana, and the  head of state of neighbouring Burundi.  
 
Genocide: AD  1994
The assassination of the president, even if secretly contrived by  extremist Hutus, is the immediate pretext for the orgy of Hutu extremism whipped  up over the following weeks. Radio broadcasts urge people to do their duty and  seek out the Tutsis and Tutsi-sympathizers living among them in their streets or  villages. On April 29 the state radio announces that May 5 is to  be the 'cleanup' day by which the capital, Kigali, must be cleansed of Tutsis.  One notorious broadcast even suggests a necessary precaution in the interests of  thoroughness; unborn children should be ripped from the wombs of dead Tutsi  women who are pregnant.
In this atmosphere the Interahamwe and a  large proportion of the ordinary Hutu population of Rwanda go to work with a  frenzy probably unparalleled in human history. Between April and July some  800,000 Rwandans are slaughtered. And this is without the modern aids of mass  destruction. The characteristic tool in Rwanda's genocide is the everyday  machete, used more normally in agriculture. The UN forces, though by now  present, are powerless to intervene.The terror of 1994 is followed by  another human disaster, as some two million refugees flee to Zaire, Burundi and  Tanzania. But these are for the most part Hutus rather than Tutsis. And they are  trying to escape from the RPF, who resume their military campaign the day after  the assassination of the president. 
 
After genocide:  AD 1994-1999
In the chaos of mid-1994 the RPF, capable of putting into the field  an extremely well disciplined guerrilla force, makes rapid progress against the  Rwandan army. By July RPF troops are in Kigali, and a provisional government is  formed. By the end of August almost the entire country is under control.  
Though largely led by Tutsis, the RPF has been from the start committed  to racial equality. This is achieved in the first cabinet, whose members reflect  the numerical balance in the country. Sixteen of its members are Hutus, six are  Tutsis. But if the RPF government can rid itself of racism, this ideal proves  very much harder to achieve in the nation.
The  immediate problem is the refugee camps just over the border in Zaire.  There are some 1.1 million Rwandans in these camps, most of them Hutus. But  these are not normal camps. They are extensions of Hutu Power in exile. Among  the ordinary refugees are members of the Interahamwe, the killers responsible  for the genocide. Who have fled over the borders to avoid the advancing RPF.
The  problem delays the return of the refugees to Rwanda, where the RPF government is  otherwise eager to receive them. When the refugees do finally begin to stream  back, late in 1996, some of the thugs of the Interahamwe are still among them.  But the more notorious killers, unable to return, stay in Zaire, where they arm  and train for violent sorties across the border.
Even the return of innocent refugees  brings its own difficulties. Those who fled in 1994 come home reasonably  quickly. They are familiar with present-day Rwanda. But the new hope offered by  the RPF brings back many whose lives and expectations have been shaped by  decades in other places - even the 'fifty-niners'  who fled from the very first manifestation of Hutu intolerance. Such long-absent  citizens can be hard to accomodate.
  
Worst of all, though, is the threat still  posed by the Interahamwe. Armed incursions across the border lead to permanent  infiltration, particularly in the northwest of the country. At times in 1998 few  districts can be considered safe outside the capital, Kigali. To the advocates  of Hutu Power this is seen as a war of liberation, similar to the one fought by  the RPF in the early 1990s. But it ensures that the virus of ethnic hatred  flourishes still in Rwanda. 
Sudden appalling acts of violence against  Tutsis and retaliation against Hutus disfigure the late 1990s, just as before in  Rwanda's short history of independence. The scale is less, but the pattern is  alarmingly familiar.
