Why a deposed king failed to reclaim his throne in two daring coups
After World War I, Charles IV of Hungary attempted to regain his crown twice, believing his people yearned for his return. Despite secret plans and dramatic train journeys, he faced a reality where neither his own regent nor the Great Powers would allow a Habsburg restoration to threaten European stability.
Following the collapse of the Austro-Hungarian Empire, Charles IV sought to return to power, despite having signed documents in 1918 that relinquished his role in state affairs. By 1920, Miklós Horthy had been named regent, and the Hungarian legislature had nullified the previous revolutionary governments. Charles, however, remained convinced that he was the legitimate monarch and that the Hungarian people and international powers would welcome him back. His first attempt, the 'Easter Crisis' of March 1921, saw him arrive unannounced at Horthy’s palace. The encounter was deeply emotional, with Charles invoking past oaths of loyalty, but Horthy refused to step down, fearing civil war and international intervention from the Little Entente.
Undeterred, Charles launched a second, more aggressive coup in October 1921. He flew into western Hungary and formed a provisional government, advancing toward Budapest with a 'royal armada' of armoured trains. The march was slow and ceremonial, allowing Horthy time to consolidate his military support. The conflict culminated in the Battle of Budaörs, a brief but deadly engagement that proved the government was prepared to use force. As the tide turned against him, Charles was forced to surrender, though he steadfastly refused to formally abdicate his throne.
The aftermath of the failed coup triggered a severe international crisis, with Czechoslovakia and Yugoslavia threatening invasion. To prevent war, the Hungarian government, led by Prime Minister István Bethlen, passed legislation in November 1921 that effectively dethroned the Habsburg dynasty. Charles was sent into exile on the island of Madeira, where his health rapidly declined until his death in April 1922. While the royalist movement never recovered, the episode highlighted the deep divide between the legitimists who viewed Charles as the rightful king and the political reality of a nation struggling to define its future without its former imperial rulers.
