Has Islam spread with the sword?

The word "sword" is not mentioned in the Noble Qur’an, not even once. The countries that did not witness any wars in the history of Islam are the countries where the majority of Muslims of the world live today like Indonesia, India, China, and others. The existence of Christians, Hindus, and others until today in the countries conquered by Muslims is an evidence on that. Whereas, Muslims who live in countries occupied by non-Muslims are only few, those countries in which genocides were committed and people were compelled to adopt their beliefs like the Crusades and others.
