In the shadowed corridors of Uganda’s postcolonial history, a insidious force has been
at work, eroding the foundations of nationhood with deliberate, unrelenting subtlety. This
“slow poison,” as articulated by the eminent scholar Mahmood Mamdani in his seminal
2025 work Slow Poison: Idi Amin, Yoweri Museveni, and the Making of the Ugandan
State, is not a literal toxin but a metaphor for the systemic fragmentation,
institutionalized corruption, and official violence that have thwarted the promise of
decolonization. Drawing from Mamdani’s firsthand account as a Ugandan exile and
intellectual, this article unmasks this creeping malaise, cross-referencing it with pivotal
case law that echoes its themes.
What is the Genesis of the Poison?
Uganda’s independence in 1962 was heralded as a triumph over British imperialism, yet
it inherited a constitution riddled with divisions that would prove fatal. The 1962
Independence Constitution, as Mamdani elucidates, reserved citizenship by birth
exclusively for members of “indigenous tribes,” excluding non-indigenous groups such
as South Asians (known locally as Bayindi) and other migrants. This legal distinction
rooted in colonial-era customary law politicized ethnicity by tethering it to territory and
authority, creating “tribal homelands” where customary laws applied discriminatorily.
Such provisions sowed the seeds of exclusion, manifesting in policies that treated non-
natives as perpetual outsiders, vulnerable to expulsion and disenfranchisement.
Mamdani’s narrative begins here, portraying colonialism not as a distant memory but as
a persistent architecture of power. He argues that British rule fragmented the population
into “martial tribes” for military recruitment, a practice that persisted post-independence
and fueled ethnic arithmetic in Uganda’s armed forces. This “slow poison” first took hold
under Milton Obote’s regime but accelerated under Idi Amin Dada, whose 1971 coup
promised reform but delivered terror. Amin’s expulsion of Asians in 1972 framed as
economic justice but laced with racial animus exemplifies this. Under Decree No. 27 of
1972, Amin revoked citizenship for over 50,000 Asians, leading to their forced departure
within 90 days. This act, while overt, was the culmination of gradual legal
marginalization, echoing Mamdani’s thesis that decolonization faltered by perpetuating
colonial indigeneity tests.
Case law from this era underscores the poison’s legal veneer. The Commission of
Inquiry into the Disappearances of People in Uganda, established by Amin in 1974 via
Presidential Legal Notice No. 2, was ostensibly a mechanism for accountability amid
rampant abductions and killings. Yet, as international observers noted, it served more as
a facade, masking the regime’s militarization of justice. In a broader sense, the
International Commission of Jurists’ 1977 report on human rights violations under Amin
highlighted how the suspension of habeas corpus and arbitrary detentions constituted a
“violation of the rule of law,” a slow erosion of judicial independence that Mamdani links
to the broader failure to dismantle colonial tribalism.
How President Museveni seals the Poison.
If Amin’s rule was a blunt instrument marked by overt brutality and economic chaos,
Yoweri Museveni’s ascent in 1986 promised antidote. Yet, as Mamdani incisively
argues, Museveni administered the slow poison with surgical precision. Seizing power
after a bush war, Museveni initially championed a “no-party democracy,” but over
decades, he transformed institutions into tools of personal rule. The book’s core
indictment: “Continuous fragmentation of the subject population, an ongoing and
seemingly endless process, reinforced by official violence and institutionalized
corruption that is, different ways of disciplining resisters and rewarding collaborators is
what I call ‘slow poison.'”
This manifests in district fragmentation, where Museveni subdivided Uganda’s
administrative units from 33 in 1986 to over 135 today, each new district reinforcing
tribal homelands and rewarding loyalists with patronage. Corruption thrives in this
balkanized landscape, as local authorities wield power over land and resources, often
through violence. Mamdani contrasts this with Amin’s failed land reforms, noting how
Museveni’s approach institutionalizes decay, turning decolonization’s dream into a
nightmare of endless division.
Ugandan case law vividly alludes to this creeping authoritarianism. In Kyagulanyi &
Another v Attorney General (Misc Cause No. 16 of 2021), the High Court ruled that
the house arrest of opposition leader Bobi Wine during elections constituted unlawful
detention, violating Article 23 of the 1995 Constitution. This case exposes the slow
poison of electoral manipulation, where security forces echoing colonial “martial tribes”
suppress dissent under the guise of order. More damning is the Supreme Court’s 2019
upholding of the 2017 constitutional amendment removing presidential age limits,
allowing Museveni indefinite rule.
