Not overlooked, but I enjoyed reading u/SickHobbit 's answers on Indonesian independence and its consequences. Both because it's something I'd been meaning to read more about; and because as OP noted the topic is not as well-known outside of Indonesia and the Netherlands as it probably should be (e.g. compared to other decolonial struggles).

Another recent and nuanced answer that I liked is u/White___Velvet on In what ways is intellectual history different from the history of ideas?

/u/Bernardito answers "What caused the New England countryside to turn against British authorities in the run up to Lexington and Concord?"

/u/cleopatra_philopater on "Cleopatra and sexuality"

/u/chocolatepot answers "Why did large age gaps in marriage go from being common to being unpopular?"

/u/cdesmoulins on Shakespeare's depiction of Richard III and Shakespeare's audience

/u/DGBD on Naming conventions in music

/u/Stormtemplar on The Gutenberg press

• /u/klesk_vs_xaero answered " I often come across claims that Italy stated to Germany that they would not be ready for war until mid-1942, but Hitler went ahead with declaring war anyway. Did Mussolini or any Italian ambassador make such a statement? or is it fiction to rationalize the poor state of the Italian Army in 1940?"

• /u/manitouwakinyan on "Why was the Rwandan Genocide such a watershed moment for the world and especially the UN?"

• /u/and__how answered "When 'The Wizard of Oz' was premiered in 1939, was this film most people's first time seeing a film in color, or had most people already had that experience by 1939? Are there any interviews with people after seeing the movie?"

I found /r/commiespaceinvader's answer to "Are there really 3 types of historian?" to be informative.
