Martin was admitted to the Virginia bar in 1869 and built a successful practice in Scottsville (once the Albemarle County seat) and surrounding counties. He became known for his expertise with land records, as well as ability to settle problems out of court. In the early 1880s, he became the district counsel for the
Chesapeake and Ohio Railway, which had bought several of the railroads destroyed in the Civil War, and which were being rebuilt. Martin became a protege of
John S. Barbour Jr., a veteran lawyer who had been president of the
Orange and Alexandria Railroad before the war and a politician and U.S. Congressman like his father (
John S. Barbour). Barbour had become affiliated with the C&O Railroad after it bought the Orange and Alexandria after the war. As well as expanding the C&O, he (with Martin's behind the scenes help) also orchestrated the rise of the state's Democratic Party at the expense of the
Readjuster Party, a coalition of
Republicans and African Americans. In 1885, Martin secured a spot on the state Democratic state central committee, the year that the Democrats secured election of former Confederate general
Fitzhugh Lee as governor. 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. Democrats again controlled both Virginia Senate seats, as well as the governorship, as they had before the war. When Barbour died in office in 1892, after just 3 years as 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. However, Hunton became embroiled in scandal, and the
Panic of 1893 led to a recession. 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). 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. In 1899, Martin faced Governor
James Hoge Tyler (a fellow Democrat whom he had supported as Lieutenant Governor and Governor in 1897), but retained his seat. In 1905, Democrats shifted from the caucus system to a primary, and Governor
Andrew J. Montague opposed Martin, as an Independent running on an anti-machine platform, but Martin won anyway, having greatly improved as a public speaker in the intervening years, and reinforcing his political organization by disenfranchising blacks and poor whites by the legislative adoption of the new state constitution in 1902. In 1910, Senator Daniel died, and Martin's ally Claude Swanson succeeded him. In 1911, Martin and Claude Swanson faced an internal Democratic party challenge from Congressman
William A. Jones, the main leader of
Progressive Democrats, and
Carter Glass, but retained their seats by a 2-to-1 margin. Senator Martin ran unopposed for re-election to the Senate in 1918. Martin and his organization worked to defeat various
Progressive forces in their own Democratic party, as well as defeat Progressive Republicans (including President
Theodore Roosevelt, who kept a camp in Virginia and noted his Confederate-sympathizing mother and her ancestors). They also worked disenfranchise African-Americans in the state, especially at the
Virginia Constitutional Convention of 1902. As shown by the multiple internal challenges, they were less cohesive than the Byrd Organization would be for decades after Martin's death. Nonetheless, Martin was also pragmatic, which assisted his rise in the Senate Democratic hierarchy. Before the 1911 election, fellow Senate Democrats elected him Minority Leader. 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). Martin first opposed
Woodrow Wilson, a former Virginian and Progressive Democrat, but when Wilson was elected (and re-elected), Martin eventually supported parts of Wilson's agenda. 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. However, Republicans regained control of the Senate in 1918, so he became Minority leader. The following year, Martin's health worsened. While he continued with some Senate business and hoped to return to Washington by the fall, he was unable to help Wilson during the peace treaty process. ==Personal life==
