Since his appointment as Crown Prince in 2017, Mohammed has spearheaded a series of social and economic reforms. These include regulations restricting the powers of the religious police and improving women's rights, such as the removal of the ban on female drivers in 2018 and weakening the male-guardianship system in 2019. Other cultural developments under his reign include the first Saudi public concerts by a female singer, the first Saudi sports stadium to admit women, an increased presence of women in the workforce, and opening the country to international tourists by introducing an e-visa system, allowing foreign visas to be applied for and issued via the Internet.
