The City of Allen was first recognized around 1870-72 and was primarily used as a railroad station. The city gets its name after Ebenezer Allen who was a Texas state attorney general and an early promoter for the Texas railroad. Ebenezer passed away in 1863. The Allen post office was established and was fully servicing mail for citizens around 1878.
The railroad brought Allen and its citizens quite a bit of commerce and the local economy boomed as a result. Local farmers were able to transport their crops to larger cities for sale on the open market. Even cattle was marketed locally as Allen became an agriculteral hub for the local citizens as well.
