For much of its history, IYM was the largest Quaker yearly meeting in the world.
In the nineteenth century, this gave the yearly meeting a reputation for being both moderate and evangelical.
[5] Forty-five congregations and two Latino church plants remained in IYM, affirming the traditional doctrinal statements of the yearly meeting and its statements on social issues, which tend to be biblically conservative and reach to the earliest days of Friends (Quakers).
The congregations left Western Yearly Meeting over that body's growing liberalism.
Yearly Meeting sessions are held at Quaker Haven Camp, near Syracuse, Indiana.
