As the Democratic Party came to power in 1950, many differences began to be seen in Turkey, and these differences have been subjected to many positive or negative criticisms both in the period and until today. Among these criticisms, there are also those related to the change in the development of Istanbul, and the reason for this change should be addressed together with the migrations to the big cities. As a matter of fact, there was an increase in the number of dwellings in Istanbul due to the increase in population with the intensified migrations in the 1950s, and this situation led to major changes in the texture of the city.

Damage to historical monuments during zoning changes in Istanbul led to negative criticisms of the Democrat Party. In the prepared article, the historical artifacts lost in Vatan and Millet Avenues are emphasized.
