Grand Ages: Medieval

To take over a town by diplomatic means you need to be friendly. Have a trading route with the town (make sure you have a trading agreement, see "Deal!" for more info. Whilst you trade, you can see the liking of the people go up (you need 95+) but if you manually trade you can specifically trade what the town needs to make the liking go up quicker though with routes it will go slow and steady as well. Next to the inhabitants you also need the "owner" to like you. Give him or her gold or goods in trade for sympathy will go quickest. When you have love from the inhabitants 95+ and liking from the town owner 80+ you can trade for the town (still give him a good offer or he will refuse your offer). Once he/she accepts you get the town. Do this 5 times in one game and the trophy will pop.
