John of Bohemia, anxious to obtain it, had engaged the hand of Margaret for his son, then but eight years of age.

It was a question in dispute whether the dukedom could descend to a female, and Albert and Otho claimed it as the heirs of their uncle.
Louis, the emperor, supported the claims of Austria, and thus Carinthia became attached to this growing power.
John, enraged, formed a confederacy with the kings of Hungary and Poland, and some minor princes, and invaded Austria.

For some time they swept all opposition before them.

But the Austrian troops and those of the empire checked them at Landau.

Here they entered into an agreement without a battle, by which Austria was permitted to retain Carinthia, she making important concessions to Bohemia.
