Horst Köhler, Germany's former president, has passed away at 81 after a brief illness.

Köhler, who served as president from 2004 to 2010, was known for his unconventional approach to politics and his focus on economic and global issues.

His controversial 2010 remark about Germany's need to protect trade routes militarily led to his resignation but is now seen as prophetic.

Köhler's career included key roles in the reunification of Germany and as head of the International Monetary Fund, where he championed poverty reduction and Africa's development.

Tributes from leaders like President Steinmeier and Chancellor Scholz highlight his dedication to social justice, democracy, and international cooperation.

Köhler's legacy as a statesman with vision and integrity will endure.
