What imperialistic forms of control did the europeans use to govern these lands?

European imperialism used diverse methods to rule colonies:

- Direct administration by governors appointed and sent by the metropolis;

- war and military occupation;

- brutal repression of resistance patriots and the civil population, or of any political dissent;

- co-optation of local elites; local elites were allowed to retain much of their power over local peoples in exchange for their submission to the central colonial authority;

- developing infrastructure and economic policies not for the development of local societies, but for the benefit of the metropolis.  

Explanation:

julius caesar turned the roman republic into the roman empire by coming in and taking the "dictator" role during the time of a civil war (elites vs lower classes) winning battles and reputation, then declaring him dictator for life
