How were the government of Venice and Florence similar?

The governments of Venice and Florence were both oligarchic, with power concentrated in the hands of a wealthy elite. Each city-state had a council that made political decisions, reflecting the interests of its dominant merchant class. Additionally, both utilized a system of checks and balances to prevent any single individual from gaining too much power, though the specific structures and titles varied between the two. Despite their differences, they both played significant roles in the development of Renaissance culture and politics.
