It's the German Unification Day on October 3rd

The German word for re-unification is Wiedervereinigung.

Sardar Patel had nothing to do with German Unification; he was primarily responsible for helping to promote Indian Unification.

The process of German unification began in the 18th century with the rise of Prussia as a dominant German power. However, the formal unification of Germany into a single nation-state occurred in 1871 following the Franco-Prussian War.
