It was a return to the original idea of the Archduke Franz Ferdinand, the union of Roumania with Transylvania, closely linked to the Monarchy.
In that case we should have lost Galicia to Poland, but a certain compensation would have been conceded to us in Roumania with her corn and oil springs, and for the Monarchy, as for the Poles, it appeared better to unite the latter collectively with Germany rather than to divide them, as suggested in the Vienna-Berlin dispute.
The plan for the annexation of Roumania presented wellnigh insurmountable internal difficulties.

Owing to her geographical position, Roumania ought naturally to be annexed to Hungary.

Tisza, who was not in favour of the plan, would, nevertheless, have agreed to it if the annexed country had been administered from Budapest and in the Magyar spirit, which meant that it would be incorporated in Hungary.

This, for obvious reasons, would involve the failure of the plan, for the Roumanians would gain no advantage from the annexation if it was to be at the sacrifice of their national independence.

On the other hand, the Austrian Ministry raised quite justifiable objections to the suggestion of a future combination that would add a rich and vast country to Hungary, while Austria would be reduced in proportion, and compensation in one or other form was demanded.
Another, but tentative, plan was to make over Bosnia and the Herzegovina definitely by way of compensation to Austria.
