Colonised Nigeria.

**The reasoning** Nigeria was colonized by **Britain** from the late 19th century until independence in 1960. Britain used a system called "indirect rule" — governing through local chiefs and emirs. Key events: the Royal Niger Company controlled trade in the 1880s, then Britain formally declared protectorates over Northern and Southern Nigeria (1900, 1906), merging them in 1914 under Lord Lugard. British rule shaped Nigeria's borders, languages (English as official), legal system, and even our federal structure. **Why the wrong options tempt you** **A) France** colonized our neighbors — Benin Republic, Niger, Chad, Cameroon (partly). Easy to confuse since they're so close. **C) Germany** briefly controlled parts of Cameroon before WWI, never Nigeria. **D) Portugal** traded along West African coasts (15th-16th centuries) but colonized Angola and Mozambique, not Nigeria. **Quick takeaway** Remember: **Britain** gave us English, indirect rule, and independence in 1960 — that's your Nigeria story. France took the neighbors, not us!
