Austria's Ultimatum to Serbia: 10 Demands, 48 Hours, WWI Is Coming

Austria-Hungary delivered an ultimatum demanding Serbia dismantle nationalist groups, allow Austrian officials to operate within Serbian borders, and surrender suspects in the Archduke's assassination. When Belgrade accepted most terms but rejected the violation of sovereignty required by point six, Austria-Hungary severed diplomatic ties and declared war four days later. This specific rejection triggered a chain reaction that pulled all major European powers into World War I.
