Petar II Karadjordjevic vs Saito Tatsuoki

Petar II Karadjordjevic became King of Yugoslavia at age 11 after the assassination of his father, King Alexander I in Marseille. A regency council led by Prince Paul governed on his behalf due to his minority.

Nazi Germany invaded Yugoslavia in response to the coup. Petar II fled the country with his government, establishing a government-in-exile in London. He remained abroad for the duration of World War II, unable to return to his kingdom.

Petar II, at age 17, participated in a military coup that overthrew the regency of Prince Paul. He assumed full royal powers and repudiated Yugoslavia's accession to the Tripartite Pact, aligning the country with the Allies against Nazi Germany.

Following World War II, the communist-led government of Josip Broz Tito abolished the Yugoslav monarchy. Petar II was formally deposed and prevented from returning to Yugoslavia, ending the Karadjordjevic dynasty's rule.

Saito Tatsuoki was defeated by Oda Nobunaga, who captured the Saito clan's castle at Inabayama and took control of Mino Province. This defeat ended the Saito clan's rule and marked the rise of Nobunaga as a major power.

Oda Nobunaga's forces stormed Inabayama Castle, the Saito stronghold, after a night attack. Saito Tatsuoki fled, and the castle fell, leading to the complete collapse of Saito power in Mino.

Saito Tatsuoki died in exile after losing his domain to Oda Nobunaga. His death marked the final end of the Saito clan's influence in Japanese politics.
