Here’s something I definitely did not know. Henry the Navigator (Prince of Portugal) became administrator general in the Order of Christ on this date in 1420. This is a position he retained until his death. And what does this mean? It was a source of funds throughout his lifetime as he explored various throughout Africa and the Atlantic Islands. From what I have read, he was a very intelligent prince who financed and donated to various educational pursuits within his country. This lets me know yet again how very little world history I know.
