In Dutch and English historiography the Dutch struggle for independence from the Spanish Crown in the 16th and 17th century was long known as the Eighty Years' War. More recently, the initial part of this period has become known as the Dutch Revolt. This concept covers the period between the initial insurrection of Netherlandish Calvinists against the regime of the Governor of the Habsburg Netherlands, Margaret of Parma, in 1566, and the conclusion of the so-called Twelve Years' Truce in 1609 between the Spanish Crown and the Dutch Republic. The historiography of this period covers both political and diplomatic developments, and events in military history. But the period of the Truce, and the military events that followed after the Truce had ended and the war was resumed, until the conclusion of the Peace of Münster in 1648, still form one continuous whole with the Dutch Revolt, and this continuous narrative, spanning the period 1566–1648, is still known as the Eighty Years' War.
