Adolphus Koopman

Adolphus Koopman (1386-1430) was a Brunanter politician and militaryman during the War of Independence.

Koopman was born in Utrecht around 1386 and came to Brunant around 1410. He was employed by the Venetians and was later in command of the garrison posted near Grijzestad. On May 22, he and his men defected over to the pro-independence side. Koopman then went to Grijzestad, where he attended the convention and later signed the Declaration of Independence. Koopman would be appointed by the Convention to lead the Brunanter army. He was handily defeated at Carona in August 1427, but he would defeat the Venetians at the Second Battle of Carona and at the Siege of Brezonde.
