He not only improved Movarounnahr and Turkestan, but also rebuilt the cities of conquered countries. He restored the cities of Baghdad, Darband and Bailakon. He built rabots, castles, bridges on the caravan routes, mosques and madrasahs, and parks and gardens in the cities. Most importantly, he ended the disunity and leadership in Iran, Azerbaijan and Iraq, and restored the ancient caravan routes connecting the East and the West. With this, he made a great contribution to the economic and cultural development of not only Movarounnahr, but also the countries of the Far and Middle East, bringing peoples and countries closer to each other. Amir Temur established direct trade and diplomatic relations with major European kingdoms such as France, England and Castile.
