This video is called Mary G. recites Ideeën by Multatuli.
Translated from Dutch NOS TV:
A letter, unknown until now, by 19th century author Multatuli has been discovered. The letter was in an attick in Almere. Multatuli, a pseudonym of Eduard Douwes Dekker, wrote the letter in 1886.
He wrote the letter to a friend, a lawyer. Multatuli writes about various subjects, including the sentencing of socialist leader Domela Nieuwenhuis to jail for insulting the king. Multatuli calls Domela Nieuwenhuis a great people’s leader.
A distant relative of the lawyer has found the letter now.
