Order of tractates

The traditional reasoning for the order of tractates (according to Rambam) is as follows.

• Yevamot is first because unlike the others, it is largely concerned with a compulsory commandment (levirate marriage
  Levirate marriage
  Levirate marriage is a type of marriage in which the brother of a deceased man is obligated to marry his brother's widow, and the widow is obligated to marry her deceased husband's brother....
  
  ) as opposed to a voluntary one.
• Ketubot follows as it signifies the beginning of married life.
• Nedarim follows because once a man is married to a woman, he has the legal right (under certain conditions) to annul her vows.
• Nazir, dealing with a special type of vow is a continuation on the subject of vows.
• The penultimate sections deal with the end of a marriage with Sotah which is concerned with infidelity and Gittin which is about actual divorce (Rambam's order swaps these two).
• Kiddushin is at the end because it follows the Scriptural order that once a woman is divorced, she can get betrothed to any man, this subsequent betrothal symbolised by the placement of Kiddushin.
