After 1945, a Hutu counter-elite developed, demanding the transfer of power from Tutsi to Hutu. The Tutsi leadership responded by trying to negotiate a speedy independence on their terms but found that the Belgians no longer supported them. There was a simultaneous shift in the Catholic Church, with prominent conservative figures in the early Rwandan church replaced by younger clergy of working-class origin. Of these, a greater proportion were Flemish rather than Walloon Belgians and sympathised with the plight of the Hutu. In November 1959, the Hutu began a series of riots and arson attacks on Tutsi homes, following false rumours of the death of a Hutu sub-chief in an assault by Tutsi activists. Violence quickly spread across the whole country, beginning the Rwandan Revolution. The King and Tutsi politicians launched a counter-attack in an attempt to seize power and ostracise the Hutu and Belgians, but were thwarted by Belgian Colonel Guy Logiest, who was brought in by the colonial Governor. Logiest re-established law and order and began a programme of overt promotion and protection of the Hutu elite. He replaced many Tutsi chiefs with Hutu and effectively forced King KigeliV into exile.
