The concept of a closed ghetto was first developed by the Venetian Republic in the 16th century. The Venetian ghetto was established in 1516, and it was the first time that a Jewish community had been forced to live in a segregated area. Other cities in Italy, Germany, and Poland soon followed suit.
The Jewish community in a closed ghetto was typically governed by a council of elders, which was responsible for maintaining order and settling disputes. The council of elders was often appointed by the local government, and it was responsible for collecting taxes and enforcing the ghetto's rules.
The Jewish community in a closed ghetto was often economically self-sufficient. Jews were often involved in trade, crafts, and moneylending. They were also often segregated from the surrounding population in terms of education and healthcare.
Closed ghettos were often the site of violence and persecution. Jews were often attacked by mobs of Christians, and they were often blamed for natural disasters and epidemics. In the 19th century, the movement for Jewish emancipation led to the gradual abolition of closed ghettos.
