Josip_Broz_Tito

Context:
Every year a "Brotherhood and Unity" relay race is organized in Montenegro, Macedonia and Serbia which ends at the "House of Flowers" in Belgrade on May 25 – the final resting place of Tito. At the same time, runners in Slovenia, Croatia and Bosnia and Herzegovina set off for Kumrovec, Tito's birthplace in northern Croatia. The relay is a left-over from Yugoslav times, when young people made a similar yearly trek on foot through Yugoslavia that ended in Belgrade with a massive celebration.
