Following King Rudolf of Habsburg's defeat of Ottokar II of Bohemia at the 1278 Battle on the Marchfeld, the territories of Austria, Styria, Carniola and the Windic March came under Habsburg control. The Diet of Augsburg in 1282 had granted these lands jointly to Rudolf's sons Albert I and Rudolf II, creating ambiguity over future governance and raising the need for a formal succession order.
On 1 June 1283 at Rheinfelden, the first Habsburg order of succession was concluded. The treaty imposed primogeniture, requiring the younger Rudolf II, then aged eleven, to relinquish all claims to Austria and Styria in favour of his elder brother Albert I. In exchange, Rudolf was to receive territories in Further Austria, though this compensation was never delivered before his death in 1290.
The primogeniture rule significantly strengthened Habsburg dynastic cohesion by enabling the accumulation of a compact hereditary territory (Hausmacht) within the Holy Roman Empire. However, Rudolf II's failure to receive promised compensation contributed directly to his son John Parricida murdering Albert I in 1308. The consolidated lands were ultimately partitioned again under the 1379 Treaty of Neuberg.
Political Outcome
Primogeniture succession established; Rudolf II relinquished rights to Austria and Styria to elder brother Albert I, consolidating Habsburg hereditary lands.
Austria and Styria held jointly by Albert I and Rudolf II following the 1282 Diet of Augsburg
Sole rule over Austria and Styria vested in Albert I under primogeniture, strengthening unified Habsburg Hausmacht
