Interesting thoughts. One word that is an understatement: Europeans “spread” their culture. It is accurate to say Europeans organized military invasions of four continents using far more superior weapons with high kills rate than people in their own countries had, occupied the, committed mass killings, and occupied those continents for decades and centuries. They killed 15 million in the Congo between 1881-1911 (Belgium); 8 million through forced labor in the Potosi silver mine conquered in Bolivia from the mid 1600s to 1700s (Spanish); killed about 100 million subcontinent Indians through mass starvation in the late 1800s to 1930s (British); killed about 3-4 million slaves in the sugar fields of Brazil from 1519-1619 (Portuguese); invaded China in the 1890s twice in the Opium Wars, once where 10 European countries went in together all the way to Beijing (Western Europe), and that was just warming up. Over a million people were killed in most countries in Southeast Asia, China, North African, the Middle East, and Eastern Europe, all because of two countries started invading them — Japan in 1937 invade China, killing millions and cutting off the heads with samurai swords when captured and Germany rolling into Czechoslovakia, Austria and Poland in 1939.
Invasion. Military invasion lead to forced adoption of cultures. It “spread”—but like the bubonic plague was spread by rats. Very unpleasantly. Euphemisms bury history.
