Northeastern became the last school in Adams or York County to field a varsity football program in 2008, giving the York-Adams Interscholastic Athletic Association its current makeup. But over the years, the league has changed names, dropped and welcomed back teams and taken in schools from neighboring leagues.

Here's a brief look at how the YAIAA came to be:

* * *

1959

The Laurel Conference, which included Central York, Dallastown, Littlestown, Susquehannock and Kennard-Dale, plays its final season of football. York Suburban played its first varsity season as an independent.
 

1960

The York County Interscholastic Athletic Association is founded with nine football teams: Central York, Dallastown, Kennard-Dale, Littlestown, South Western, Spring Grove, Susquehannock, West York and York Suburban. It's the first year of varsity football for South Western and Spring Grove.
 

1964

Red Lion, from the Conference of Roses, and Hanover, from the South Penn Conference, join the YCIAA, bringing the total to 11 teams.
 

1966

Both Kennard-Dale and Littlestown leave the league. Kennard-Dale doesn't play football again until 1976. Littlestown plays an independent schedule before joining the Blue Mountain League.
 

1970

Vo-Tech (now York County Tech) increases the league's total to 10 teams.
 

1974

Dover makes the YCIAA an 11-team league again by coming on board, and the league is split into two divisions.
 

1976

Kennard-Dale comes back to the league, and Eastern York and York Catholic become the 13th and 14th teams to join the league.
 

1981

William Penn joins its neighbors in the YCIAA, coming from the Central Penn League.
 

1992

Delone Catholic, Littlestown and New Oxford all come to the league, now known as the York Area Interscholastic Athletic Association, from the Blue Mountain League.
 

2004

Bermudian Springs and Biglerville leave the Mid-Penn Conference to join the league now known as the York-Adams Interscholastic Athletic Association. Fairfield, another Adams County school, also comes on board after completing its first varsity season as an independent.
 

2008

Northeastern becomes the 22nd varsity football program in the YAIAA. It is the last public school in York or Adams counties to launch a football program.

2014

Gettysburg leave the Mid-Penn Conference to join the league, becoming the 23rd varsity football program in YAIAA.
