Some presidents did not use a Bible to take the oath of office, including Theodore Roosevelt, who did not use anything when he was sworn into office in 1901, and John Quincy Adams, who chose a legal book for his 1825 swearing-in, to signify his responsibility to uphold the U.S. constitutional law.

There’s a unique family backstory behind the holy book that the President-elect will use for his second inauguration on Monday.

President-elect Donald Trump will use two Bibles to culminate the 60th Presidential Inauguration. He is not the first to do so, nor to use the historical Bible he chose.

The president-elect eschewed the star-spangled “Trump Bible” in favor of volumes with personal and national history.
