Lukšaitė was born on 2 February 1940 in Kaunas to the family of banker and cultural historian Meilė Lukšienė. She studied at the National M. K. Čiurlionis School of Art before enrolling at Vilnius University to study history. She graduated in 1962 and worked as a teacher in Trakų Vokė until 1964 when she became an aspirant (doctoral student) at the Lithuanian Institute of History.

She also lectured at the Vilnius Academy of Arts (1985–1990), Vytautas Magnus University (1995–2002), and Vytautas Magnus University (2001–2007).

The monograph sold out quickly and Lukšaitė received the for the book. The monograph was translated to German in 2017. A shortened Lithuanian version for the general public was also published in 2017.
