Albertine line

The Albertinian line was a line of the Habsburg dynasty, begun by Duke Albert III of Austria, who, after death of his elder brother Rudolf IV, divided the Habsburg hereditary lands with his brother Leopold III by the 1379 Treaty of Neuberg. The branch finally became extinct in the male line with the early death of Ladislaus the Posthumous in 1457.

According to the terms of the treaty, Albert was the ruler over the Duchy of Austria proper, while the southern territories (Inner Austria) were ruled by his brother - Leopold III, ancestor of the Leopoldian line. Albert ruled over Austria until his death in 1395. His only son and heir was also called Albert, he took the rule over his territories as Albert IV and quickly came to terms with his Leopoldian cousins William, Leopold IV, Ernest and Frederick IV. When Albert IV died in 1404 he left a minor son - Duke Albert V of Austria, who remained under the tutelage of his Leopoldine uncles William (until 1406) and Leopold IV (until 1411).

Having assumed the rule over Austria, Albert V in 1421 married Elizabeth of Luxembourg, the only child of Emperor Sigismund. After Sigismund's death in 1437, he was crowned King of Hungary and King of Bohemia. In 1438 he also was elected King of the Romans (as Albert II) and Emperor-to-be, anticipating the powers of the later Habsburg Monarchy, however, he died the next year. The Hungarian throne passed to Polish king Władysław III against the fierce resistance of Albert's widow Elizabeth.
