I am a History undergrad and originally picked the major because I was passionate about the topic. I quickly got caught up with life though and ended up not learning much during my time in university and ultimately ignored my original passion for the subject. Recently through some podcasts and a growing interest in geopolitics, this passion has been somewhat reignited and I'm looking to bolster a broader knowledge of the subject.

I'm looking for book recommendations that are history essentials. Magnum opuses that everyone interested in history should read, both classics and more recent works. Thanks!
