After General Lee's surrender at Appomattox Court House, Martin returned home, but that fall began studies at the University of Virginia.
He became a member of the Phi Kappa Sigma fraternity, but withdrew after two years because his father's death forced him to take charge of the store and mill and support the family.
Martin would later remain connected with the university and served a term on UVa's Board of Visitors, but in the short run read law at night.
Two years later, Martin successfully promoted the Senate candidacy of John W. Daniel of Lynchburg, to replace Readjuster William Mahone (another former Confederate general), although Barbour wanted the seat.
In 1889, when the Readjuster Party's other leader, Senator Harrison H. Riddleberger chose not to run for re-election (he would die the following year), Barbour won the seat and became a U.S.
Senator, the organization that he and Martin had nurtured initially allowed former CSA General (and Virginia lawyer and Congressman) Eppa Hunton to succeed him.
Assisted by campaign contributions from the C&O and other railroads (made more important because of the economic recession, as would be revealed during the 1911 campaign), and with the assistance of Congressmen Henry D. Flood and Claude Swanson (who later became Governor) as well as elected officials in many of Virginia's counties, Martin secured 66 votes in the Democratic legislative caucus (compared to 55 votes for Fitzhugh Lee, who gave speeches throughout the Commonwealth but proved lethargic in securing legislative support).
[6] Thus, despite relatively poor oratorical skills, Martin upset the favorite in December 1893, and the following year formally secured election to the U.S. Senate, helped by his new marriage.
Re-elected several times (first through the legislature and later by voters after the seat became subject to direct election), Martin represented Virginia in the United States Senate for nearly twenty-five years.
He withdrew as a candidate for re-election to that post in 1913, and in 1915 spent most of the campaign season in Albemarle County, since his wife's tuberculosis had worsened (and she died by year's end).
[5] After his wife's death in 1915, Martin devoted himself to Senate business, becoming Majority leader in 1917, and securing the declaration which supported American entry into World War I.
Possessing decided literary talent, as well as being an accomplished swimmer and equestrian, she had numerous published poems and prose articles, many admired for their beauty of thought and expression.
