==Mexican War, 1846-1848==
The Mexican War (also known as the Mexican-American War, the First American Intervention, and the U.S.–Mexican War) resulted from the annexation of Texas by the United States in 1845. Thirty-five thousand U.S. Army troops and 73,000 state volunteers fought in this war. Most volunteer regiments were from southern states, such as Louisiana, Tennessee, Missouri, and Texas. The war took place from April 25,1846 to February 2, 1848.

War with Mexico was declared on May 13, 1846. However, units of soldiers were organized in Texas in the fall of 1845. Volunteer units were organized from  Alabama, Arkansas, California, Florida, Georgia, Illinois, Indiana, Kentucky, Louisiana, Maryland and the District of Columbia, Massachusetts, Michigan, Mississippi, Missouri, New Jersey, New York, North Carolina, Ohio, Pennsylvania, South Carolina, Tennessee, Texas and Virginia. One unit was composed of Indians and one of members of The Church of Jesus Christ of Latter-day Saints-the Mormon Battalion.
 
Regular Army units included the 1st Regiment of Dragoons, 2nd Regiment of Dragoons, 3rd Regiment of Dragoons, Regiment of Mounted Riflemen, 1st Regiment of Artillery, 2nd Regiment of Artillery, 3rd Regiment of Artillery, 4th Regiment of Artillery, 1st through 16th Regiments of Infantry, Regiment of Voltigeurs and Foot Riflemen.
 
=== Step 1 - Identify an ancestor who may have served in the Mexican War ===
 
Look at your ancestors' information to determine which match the following criteria:
 
{{Block indent|- '''Ages:''' Most soldiers and sailors were men between their late teens of early to mid twenties so they would have been born in the 1820s or earlier. }}
 
{{Block indent|- '''Death: '''Did your ancestor die between April 1846 and February 1848? Did he die in Mexico or a Southern state or western state different than where his family was living? Most of the soldiers enlisted in a volunteer military unit where from a southern or western state. Others may have joined the Regular Army or navy.}}
 
{{Block indent|- '''Family Members:''' Check with other members of your family to see if they have and records of records of information of Mexican War service.}}
 
=== Step 2 - Identify the county and state where your ancestor lived  between 1845-1848  ===
 
If you do not know the county and state where your ancestor lived at the start of the war, check the following:
 
*The {{RecordSearch|1786457|United States Census, 1840}} for his family.
 
=== Step 3 - Find your Ancestor's Military Unit or Naval Service ===
 
Your soldier's military unit are often needed to find his records and to recognize him in the records.
State volunteer regiments many have a published history written or compiled by a veteran, a descendent or interested individual. The histories may have biographical data on officers and unit rosters of members, and they often provide clues to the town or county where the soldiers were living when they enlisted. Published county histories may also have information on military units raised in their locality. See also the Wiki article [[United States, Mexican War Military Unit Names - FamilySearch Historical Records]]
 
*'''Search the National Archives Index to Compiled Military Search Records'''
The index is arranged in alphabetical order by the soldier's surname. The soldiers name will be the one he most often went by or found in the original records that were carded. Names could also be listed by initials. The index card will identify company and military unit and rank of each soldier entering the service and at discharge. A soldier could have served in multiple units and a separate compiled military service record would exist for each unit. A cross reference may be found on some cards for multiple spelling or service in additional units. A volunteer may have enlisted under a different name or alias.
