The Smithsonian's online magazine has released its top ten history books of 2023. It's a heavily American list both by author and subject, with some British titles for a bit of diversity. Still some pretty substantial titles. David Grann's very popular The Wager; Jonathan Eig's King on Martin Luther King; Mary Beard's Emperor of Rome; The World: A Family History by Sebag Montefiore; among others.
For some Canadian content, best consult Canada's History's annual Book and Gift Guide.
Some notable Canadian history this year would include John Ibbitson's The Duel (Diefenbaker v Pearson); Ken McGoogan's Searching for Franklin, Leanne Leddy's Serpent River Resistance (actually from 2022); Owen Shield's Canada in Afghanistan; Matt Burnett and Robert Engen's Through Their Eyes (a graphic novel of the First World War battle Hill 70), Charlotte Grey's Passionate Mothers, Powerful Sons (Roosevelt and Churchill's mothers), John Vaillant's Fire Weather, and Stephen Bown's Dominion (the CPR and Canada), to mention a few of the prominente. An advantage of the Canada's History Book Guide is the attention it gives to less widely promoted regional and local histories, indigenous history, and art history
