Which amendment established the process for presidential succession?

The 25th Amendment to the U.S. Constitution specifically addresses presidential succession and provides a clear process for what happens when a president is unable to fulfill their duties. Ratified in 1967, it outlines procedures for both the transfer of power in cases of death, resignation, or removal of the president, and for situations where the president is incapacitated.

The amendment specifies that if the president is removed from office, dies, or resigns, the vice president becomes the president. Additionally, it allows for the appointment of a new vice president when there is a vacancy. Furthermore, if a president is unable to perform their duties, the amendment provides a mechanism for the vice president and a majority of the cabinet to temporarily transfer power to the vice president until the president can resume their responsibilities.

In contrast, the 22nd Amendment limits the number of terms a president can serve, the 20th Amendment deals with the dates for the start of presidential and congressional terms, and the 19th Amendment grants women the right to vote. Thus, they are unrelated to the process of succession in the presidency.
