Today:
Welcome to this week's instalment of /r/AskHistorians' Sunday Digest (formerly the Day of Reflection). Nobody can read all the questions and answers that are posted here, so in this thread we invite you to share anything you'd like to highlight from the last week - an interesting discussion, an informative answer, an insightful question that was overlooked, or anything else.
The Rundown:
/u/Georgy_K_Zhukov answered "How easy was it to provoke somebody for a duel in 18-19th century Europe? How hard was it to evade a fight?"
/u/astrogator answered "What were ancient civilisations like with charities? Did the Romans or mayans have charities in the sense we do today?"
/u/gtferinyes on "Why is the United States Marine Corps considered 'special?' in comparison to the other branches?"
