Belgian colonialists, initially favouring the Tutsi minority due to their established socio-political dominance, switched their allegiance to the Hutu majority in the late colonial era. This shift, influenced by global pressures advocating majority rule and anti-colonial sentiments, drastically altered Rwanda's political landscape. With Belgian support, Hutu elites initiated what is now known as the Hutu Revolution from 1959-1961, leading to the overthrow of the Tutsi monarchy. The period witnessed significant violence, causing the death and displacement of many Tutsis. By the time of Rwanda's independence in 1962, Hutus had firmly entrenched their political control, heralding a new era in Rwandan politics.

The 'Ubuhake' system was a hierarchical client-patron relationship where Hutus would pledge their service to Tutsi patrons in exchange for economic favours, often in the form of cattle. While this system offered immediate benefits, such as resources and protection, its long-term implications were profound. It further embedded the existing socio-political hierarchies by creating a cycle of dependency wherein the Hutus were invariably subordinated to their Tutsi lords. This systemic subordination not only created an economic disparity but also a social one, whereby Hutus were continuously reminded of their 'inferior' status, laying fertile ground for future animosities.

Introduced by the Belgians in the 1930s, ethnicity-specified identity cards were a particularly pernicious instrument. While Hutu-Tutsi distinctions had historical underpinnings, the identity cards institutionalised and cemented these divisions. By assigning and recording one's ethnicity, what was once a fluid and malleable identity became a fixed, inescapable label. These cards not only validated spurious racial theories the Belgians had introduced but also made it easier to segregate, discriminate, and, during the 1994 genocide, systematically target individuals. In essence, these cards transformed personal identities into political tools, further embedding the ethnic divide in Rwanda's societal fabric.

In many agrarian societies, livestock, especially cattle, was synonymous with wealth due to their multifaceted utility. In Rwanda, cattle weren't just sources of milk, meat, and hides but also played central roles in socio-cultural practices. They were pivotal in ceremonies, marriage dowries, and as tributes. As cattle herders, Tutsis had direct control over these valued assets, thus placing them in an advantageous position. The socio-economic system was such that cattle became both a literal and symbolic representation of affluence and authority, which, in turn, significantly influenced socio-political dynamics and the resulting hierarchies in Rwandan society.

Historically, the distinctions between Hutus and Tutsis weren't rigidly ethnic but more occupational. Hutus, primarily agriculturists, and Tutsis, chiefly cattle herders, coexisted with relative fluidity in their identities. This fluid nature was such that acquiring cattle or changing occupations could sometimes facilitate a shift in one's ethnic classification. Over time, however, as cattle became a symbol of wealth and prestige, the Tutsis, despite being a minority, ascended in social and political prominence, leading to a more definitive socio-economic divide. This status quo, which had centuries of establishment, was further solidified and exploited during the colonial era.
