Over 2.8 million men (and a few hundred women) served in the Union and Confederate armies during the Civil War, primarily in "Volunteer" Army units. About half of the volunteers on both sides had been farmers before joining the Army, with the remainder coming from a wide variety of occupations and backgrounds. Soldiers ranged in age from 18 to 45, with most being under 30; young boys enlisted as buglers and some older men joined as privates.
In both armies, the vast majority of Civil War soldiers were white. According to the National Park Service, the 2,672,341 enlistments for the Union Army consisted of:
Estimates of enlistment strength for the Confederate Army range from 750,000 to 1,227,890. Soldier demographics for the Confederate Army are not available due to incomplete and destroyed enlistment records.
Before May 22, 1863, when the U.S. War Department established the Bureau of Colored Troops, black men were not eligible to serve as soldiers in the Union Army. But throughout the conflict, blacks contributed in other capacities, such as constructing entrenchments or performing camp duty or other labor for both the Union and Confederate forces. By the end of the war, 178,975 enlisted men served in the U.S. Army as members of the U.S. Colored Troops. In addition, three regiments of Native Americans, the Indian Home Guard, fought for the Union in the western theater of the war.
Non-native born soldiers made up as much as a quarter of the Union Army, and a lesser number served on the Confederate side as well. In the Union Army, Germans were the largest group of foreign-born soldiers, followed the Irish, Canadians, and English. Other nationalities represented included Scandinavians, Swiss, French, Italians, Mexicans, and Poles. Regiments were often formed entirely of men from one of these countries.
Over 400 women also dressed as men and served in the army. Many of them, like Jennie Hodgers who served in the 95th Illinois as Albert Cashier, were not revealed to be women until after the war was over.
The sprawling nature of the conflict is reflected in the reams of records it generated, which can be both a blessing and a curse to genealogy researchers. Take advantage of the many guides available for Civil War research (listed below) to make the most effective use of the voluminous records described below.
ONLINE GUIDES
PRINT GUIDES AT NYPL:
The Soldiers and Sailors database is a searchable name index of those who served in both the Confederate and Union armies, and is freely available online through the National Park Service.
This free online database combines data from multiple microfilmed indexes to compiled service records for various groups of soldiers (Regular, Volunteer, Union, Confederate and "Colored") to provide a single, unified index for all soldiers and sailors serving in the Civil War.
The names of all soldiers in the database are linked to a regiment, which provides an overview of the unit, including the battles in which it participated. Researchers can also link to a list of all the other soldiers serving in that regiment, which may help you identify other ancestors who participated in the war.
This index is also available through Family Search as the United States Civil War Soldiers Index, 1861-1865

NOTE: Confederate pension files are not held by the federal government and are described in the State Records box, below.
The first pension law for Union widows, orphans and disabled soldiers was enacted in 1862. Until 1907, death and disability were the only grounds for a pension. Later acts were more generous: the Act of May 11, 1912, granted service-based pensions to most veterans of the Civil War and Mexican War. Widows’ compensation became more generous in 1916 and 1920.
The pension files for Union veterans were not microfilmed and most have not yet been digitized, but there are multiple online and print indexes that can help you determine whether a veteran or widow applied for a pension:
To better understand the differences, and determine which one(s) you should use, consult the useful NARA blog Pension Indexes Examined. When searching these indexes, it’s helpful to know the soldier’s unit, state and widow’s name to ensure you’ve identified the right man.

PENSION LISTS
On December 8, 1882, the U.S. Senate required the Secretary of Interior to submit a list of pensioners on the roll January 1, 1883. The completed list was published in 1883 in five volumes as "List of Pensioners on the Roll, January 1, 1883...". The majority of pensioners listed were from the Civil War.
These volumes are available online and at NYPL:
PENSION CORRESPONDENCE

Both the Confederate and Union armies enacted conscription laws when the number of volunteer soldiers became insufficient.
UNION DRAFT RECORDS
The first Union registration took place July 1, 1863. Three smaller enrollments followed. For eligibility purposes, men were divided into classes. Those age 20 to 35 years, plus unmarried men age 36 to 45, were designated Class I. Nearly everyone else was Class II.
Not everyone who registered ended up serving in the war. Those in Class II were rarely made to serve. Each community and state was responsible for filling a quota of men. If they could raise that number with volunteers, no one needed to be drafted, so volunteers were heavily encouraged. Some states, like Massachusetts and Ohio, never had to call up draftees.
Even if they were drafted, men could be exempted from service if they were:
Draftees could also avoid service by furnishing a substitute or paying a $300 fee. Information on how to investigate this possibility can be found in Researching Civil War Draft Records in NARA’s Regional Archives.

CONFEDERATE DRAFT RECORDS
There are no consolidated lists of Confederate registrations. Each Southern state conducted its own drafts. Many times, troops raised by conscript were merged with existing units. Relatively few Confederate conscription registers survive today, and those that do can be difficult to find. We identified the following:

Confederate veterans were not eligible for federal pensions. But many of the previous Confederate states authorized pensions for Confederate soldiers at the state level. Confederate veterans were eligible to request a pension from the state where they lived at the time of application, even if they enlisted and served under another state.
Like the federal government, most Southern states initially offered pensions only for death and disability. General service pensions came later, and many required applicants to prove financial need. Some Southern states have suffered record losses; for example, most South Carolina pensions issued before 1919 were lost in a fire.
The following state awarded confederate pensions:

The state of New York contributed the greatest number of men to the Union Army during the Civil War and sustained the heaviest losses of any state in the Union.

Types of State Civil War Resources
State records relating to the Civil War are generally held by the State Archives and/or State Library. Additional records are often available at state and local historical societies.
The most common types of records you'll find at these repositories include:
Some of these records are now available online. For example, the New Jersey Department of State has created free, online searchable databases for the following records:

Links to some additional digitized state records are available at Online Civil War Indexes and Records. Be aware that many of the state military "records" digitized on Ancestry are actually reproductions of the printed indexes, rather than collections of original documents.
RESOURCES AT NYPL
The Library holds hundreds of indexes, abstracts, rosters and other record summaries arranged geographically, by state, county and sometimes even by towns. The collection is national in scope and includes states across the country. The following small list of representative titles is just meant to illustrate the kind of materials we have.
