This region comprised most of the modern states of Belgium and Luxembourg, as well as parts of northern France, the southern Netherlands, and western Germany, with the capital being Brussels.
A common administration of the Netherlandish fiefs, centered in the Duchy of Brabant, already existed under the rule of the Burgundian Duke Philip the Good with the implementation of a stadtholder and the first convocation of the States General of the Netherlands in 1464.
Maximilian prevailed with the support of Duke Albert III of Saxony and his son Philip the Handsome, husband of Joanna of Castile, could assume the rule over the Habsburg Netherlands in 1493.
The Habsburgs often used the term Burgundy to refer to their hereditary lands (e.g. in the name of the Imperial Burgundian Circle established in 1512), actually until 1795, when the Austrian Netherlands were lost to the French Republic.
Between 1555 and 1556, the House of Habsburg split into an Austro-German and a Spanish branch as a consequence of Charles's abdications: the Netherlands were left to his son Philip II of Spain, while his brother King Ferdinand I succeeded him as Holy Roman Emperor.
In January 1579 the seven northern provinces formed the Protestant Union of Utrecht, which declared independence from the Spanish branch of the Habsburgs as the Republic of the Seven United Netherlands by the 1581 Act of Abjuration.
The couple's rule brought a period of much-needed peace and stability to the economy, which stimulated the growth of a separate South Netherlandish identity and consolidated the authority of the House of Habsburg reconciling previous anti-Spanish sentiments.
