The Corporate Yoke started on 21 December 1951 when several major companies in Iansisle, led by Royal Mining and Manufacturing and the East Gallaga Company, conducted a secret coup. Using hostages, the Corporatists took control of the heads of government in Iansisle and used them to put down increasingly violent strikes and revolts in Eastern Ianapalis.
However, by June 1952, the disturbances were becoming too large to be contained, especially after the Earl of Inswick snuck a message out of the country. Charles Bradsworth arrived from Larkinia late that month and started organizing a proper resistance. On 3 August 1952, the Corporate Yoke was ended and the companies pulled their forces out of Ianapalis.
