 Frederick was now the undisputed head of the Habsburg dynasty, though his regency in the lands of the Albertinian Line (Further Austria) was still viewed with suspicion.As a cousin of late King Albert II, Frederick became a candidate for the imperial election.On 2 February 1440, the prince-electors convened at Frankfurt and unanimously elected him King of the Romans as Frederick IV; his rule was still based on his hereditary lands of Styria, Carinthia and Carniola, or Inner Austria.
