Szoftver PC, the only question is whether you are simply ignorant or willfully so? Portugal began bringing African slaves to Europe in 1444. The Trans Atlantic Slave Trade began in 1526 when Portugal Brought hundreds of slaves to Brazil. Portugal had slaves with them in 1526 when they landed in Florida. Spain brought slaves to Saint Augustine, FL in 1565. Britain brought slaves to Jamestown in 1619.

Well before 1800, Lisbon was well over 10% Black due to the number of free and enslaved Black people. Portugal brought their first slaves to Japan and China in the mid to late 1500s. The European ships all had Black crew members. The Jesuit priests in Japan engaged in the slave trade of Japanese and Kpreans and had Black slaves and servants of their own.

Back to Europe. Black people had existed in Rome since before Jesus. By 1800 there were Black people in every European country with the possible exception of Iceland. Because there's this thing called the Internet. I checked on Iceland who didn't get their first Black settler until 1802.

Since you're the fount of all knowledge. When do you think Black people arrived in Europe and in Japan? Or you could just spout whatever comes to your mind as if it were knowledge.
