According to this article probably the oldest Romanian protester is 101 years old:
Philosopher Mihai Sora, aged 101, famous for attending numerous street protests in the past year, recounted the incidents involving him and the gen dares during the Wednesday’s manifestation in Victoriei Square, Bucharest.
I am wondering if there is any reference (document) about an older protester. Restrictions:
- participation after 1900
- political protest
- participation out of his/her own will
- must have a minimum lucidity (e.g. understand the reasons for being at the protest)
Note: age is considered at the moment of protest
Question: Who is the oldest known political protester?
