March 6:
There were lots of treaties and edicts today, but none of them seemed particularly important.
A.D. 1479: Portugal exchanges the Canary Islands with Castile for territory in West Africa.
A.D. 1965: The first non-stop helicopter crossing of North America.
A.D. 2013: Syrian rebels capture Ar-Raqqah, their first major city.
This is a dull day for history.
