Hi, I am finishing off a masters degree in medieval history, and have an idea for a phd. My question is, would I need to be proficient in Latin? I have been fortunate in my masters to find English translations of most of the sources I'm looking at, but I'm guessing for a phd I would need to study a greater range of materials. My Latin is almost non-existent, though I am considering doing a course in Latin before applying for a phd.

Thanks in advance for any advice!
