There have been numerous cities throughout history that have been divided due to various reasons such as political conflicts, wars, or social and economic factors. Some notable examples include:

1. Berlin, Germany: After World War II, Berlin was divided into East Berlin (controlled by the Soviet Union) and West Berlin (controlled by the Allies). This division lasted from 1949 to 1990, until the Berlin Wall was dismantled and Germany was reunified.

2. Jerusalem, Israel/Palestine: Jerusalem has been a contentious city, divided between Israel and Palestine. The eastern part of the city is predominantly Arab and was occupied by Jordan until the Six-Day War in 1967, when Israel gained control. The division of Jerusalem remains a major issue in the Israeli-Palestinian conflict.

3. Nicosia, Cyprus: Nicosia, the capital of Cyprus, has been divided since 1974 when Turkish forces occupied the northern part of the city. The division is a result of the ongoing conflict between Greek Cypriots and Turkish Cypriots.

4. Belfast, Northern Ireland, UK: During the Troubles (1968-1998), Belfast experienced deep sectarian divisions between the Protestant and Catholic communities. Barriers known as "peace walls" were erected to separate the neighborhoods, although efforts have been made to reduce and remove them since the Good Friday Agreement in 1998.

5. Sarajevo, Bosnia and Herzegovina: During the Bosnian War (1992-1995), Sarajevo was divided into Serbian-controlled areas and Bosnian-controlled areas. The city experienced a long and brutal siege, resulting in significant damage and loss of life.

6. Nicosia, Cyprus: Nicosia, the capital of Cyprus, has been divided since 1974 when Turkish forces occupied the northern part of the city. The division is a result of the ongoing conflict between Greek Cypriots and Turkish Cypriots.

7. Belfast, Northern Ireland, UK: During the Troubles (1968-1998), Belfast experienced deep sectarian divisions between the Protestant and Catholic communities. Barriers known as "peace walls" were erected to separate the neighborhoods, although efforts have been made to reduce and remove them since the Good Friday Agreement in 1998.

8. Sarajevo, Bosnia and Herzegovina: During the Bosnian War (1992-1995), Sarajevo was divided into Serbian-controlled areas and Bosnian-controlled areas. The city experienced a long and brutal siege, resulting in significant damage and loss of life.

9. Mostar, Bosnia and Herzegovina: Mostar was divided along ethnic lines during the Bosnian War. The division was particularly evident with the destruction of the iconic Old Bridge, which separated the Bosniak (Bosnian Muslim) and Croat communities. The bridge has since been rebuilt, but the scars of division remain.

These are just a few examples, and there have been many other cities throughout history that have experienced division and conflict.
