Having seen the title of the post, many probably thought that it would be about a wild, backward, medieval country with even worse living conditions than now. But you are wrong. Some time ago, it was an absolutely different country. Afghan women made a career in medicine, went to the movies and studied at the universities of Kabul. Afghan factories produced fabrics and other goods. There was law and order and the government could implement such large infrastructure projects as the construction of hydroelectric plants and roads (though not without help from outside). Ordinary people had hope for the future... All this was destroyed by thirty years of war.
The campus of the University of Kabul has changed little since then. It's people who have changed. In the 50s-60s, the students preferred Western style clothes, and the young people of both sexes could freely communicate with each other.
