mend one's fences

Improve poor relations; placate personal, political, or business contacts. For example, The senator always goes home weekends and spends time mending his fences. This metaphoric expression dates from an 1879 speech by Senator John Sherman in Mansfield, Ohio, to which he said he had returned "to look after my fences." Although he may have meant literally to repair the fences around his farm there, media accounts of the speech took him to mean campaigning among his constituents. In succeeding decades the term was applied to nonpolitical affairs as well.

mend one's fences, to

To strengthen one’s position by reestablishing good relations among one’s supporters. The term apparently came from a speech by Sen. John Sherman to his neighbors and friends in 1879 in Mansfield, Ohio, in which he said, “I have come home to look after my fences,” presumably literally meaning the fences around his farm there. (Indeed, mending fences is a major and time-consuming chore for nearly all American farmers.) However, the newspaper reports of the speech interpreted it as a political statement that meant Sherman was really home to campaign among his constituents. The term continued to be used in this way, with repair and mend substituted for look after. In the twentieth century it was broadened to mean placating personal, business, or professional contacts who might have felt neglected or offended and trying to regain their support. Vice President Al Gore used it after his defeat in the 2000 presidential election, saying he planned to mend his fences.
