Holladay is a city in central Salt Lake County, Utah, United States. It is portion of the Salt Lake City, Utah Metropolitan Statistical Area and abuts the Wasatch National Forest. The population was 31,965 at the 2020 census, a significant mass from 14,561 in 2000 gone the first area incorporated from Salt Lake County. The city was incorporated on November 29, 1999, as Holladay-Cottonwood, and the reveal was abbreviated to Holladay on December 14 of that year. It was reported in the 1990 census as the Holladay-Cottonwood CDP.

On July 29, 1847 a group of Mormon pioneers (members of the Church of Jesus Christ of Latter-day Saints) known as the Mississippi Company, among them John Holladay of Alabama, entered the Salt Lake Valley. Within weeks after their arrival, they discovered a free-flowing, spring-fed stream, which they called Spring Creek (near what is now Kentucky Avenue). While most of the work returned to the main harmony in Salt Lake City for the winter, two or three men built dugouts along this stream and wintered over. Thus, this became the first village traditional away from Salt Lake City itself. In the spring, a number of families hurried out to build homes and bland the land. There were numerous springs and ponds here and grasses and wild flowers were abundant, making this a desirable area for settlement.

When John Holladay was named as the branch president of The Church of Jesus Christ of Latter-day Saints, the village took on itself the herald of Holladay’s Settlement or Holladay’s Burgh. John Holladay’s intimates dates to the before 18th century in Virginia. His ancestors were signers of the South Carolina Declaration of Independence and fought in the Revolutionary War. He is a cousin to Ben Holladay, The Stagecoach King, who traded like the LDS and ran his Denver-San Francisco stage heritage through Salt Lake. It is not known if they were in contact. John and his father Daniel, a Revolutionary War veteran, pioneered in Alabama before John’s conversion to Mormonism. A year past the first LDS migration, in the spring of 1846, he departed west in the announce of his extended family joining additional converts that made in the works the Mississippi Company led by John Brown. They had been led to expect to meet the main party upon the trail but after going as far afield as Laramie without a sign of them they went south and wintered at Pueblo, Colorado where they were well along joined by the Mormon Battalion sick detachments. They had not gotten the word that Brigham Young’s departure had been delayed by a year.

Holladay is the oldest at all times inhabited treaty in Utah, since Salt Lake City was lonely for a times in 1857 later than Johnston’s Army occupied the city.
