Context and question: Karl Marx published the Communist Manifesto in February 1848, with little attention. However, a few days later the French Revolution of 1848 broke out, which replaced the monarchy of Louis Philippe with the Second French Republic.

Who wrote the Communist Manifesto?
Answer: Karl Marx

Question: Rebetiko, initially a music associated with the lower classes, later (and especially after the population exchange between Greece and Turkey) reached greater general acceptance as the rough edges of its overt subcultural character were softened and polished, sometimes to the point of unrecognizability.

The leading performers of the genre include Apostolos Kaldaras, Grigoris Bithikotsis, Stelios Kazantzidis, George Dalaras, Haris Alexiou and Glykeria.

Problem: Gamal Abdel Nasser:

In 1928, Nasser went to Alexandria to live with his maternal grandfather and attend the city's Attarin elementary school. He left in 1929 for a private boarding school in Helwan, and later returned to Alexandria to enter the Ras el-Tin secondary school and to join his father, who was working for the city's postal service. It was in Alexandria that Nasser became involved in political activism. After witnessing clashes between protesters and police in Manshia Square, he joined the demonstration without being aware of its purpose. The protest, organized by the ultranationalist Young Egypt Society, called for the end of colonialism in Egypt in the wake of the 1923 Egyptian constitution's annulment by Prime Minister Isma'il Sidqi. Nasser was arrested and detained for a night before his father bailed him out.

Where did young Nasser witness demonstrations?

A:
Manshia Square
