Hell during the 2nd Opium War when the allied forces (mostly British and French) sacked Beijing at least looted as much as possible before they started burning shit for torturing their diplomats.

I still find the reason why the British have so much Greek artifacts funny as it was because they asked the ottomans permission to make casts of vases and works so they wouldn't be lost if a disaster happened, the ottoman ruler agreed and sent an edict saying not to bother the British if you see them with Greek vases and artifacts to which the British went 'wait you're not going to stop, ask or get in our way if we take these artifacts, fuck casts grab the originals!'
