European Colonialism was in part a trade war between the rising European empires. It started largely about ports and trade routes before the Berlin Conference that regulated trade and colonisation in 1885. Less than 30 years before World War I rang the first death knells for Imperialism. The Mosquito Coast was an area on the coast of present-day Nicaragua and Honduras. A somewhat less appealing nickname than the Ivory Coast. When the first Spanish Conquistadors arrived in Nicaragua, they fought each other in what was known as 'The War of the Captains'. Two of the first two competing settlement were set up at Grenada on Lake Nicaragua, and Leon near Lake Managua. The winner became the colonies first governor. Without women in their parties, the colonists took local indigenous wives which led to a multi-ethnic population mix over time.
