How to Get Horses in "Civilization IV"by Joshua Phillips ; Updated September 22, 2017
"Civilization IV" allows a player to build a culture from the very beginning of civilization. When you first begin the game, even such simple tasks as knowing how to ride a horse are out of your civilization's reach. By learning the right technological skills, your civilization can learn to cultivate a wide variety of animals such as cows, sheep and horses. Once your civilization has horses, new possibilities open up such as the horseback archer, giving you an advantage over your enemies.
Click on the research bar at the top of the screen to open the technology tree window.
Select "Agriculture" to learn this technology. Based on various factors, such as the amount of people in your town, it can take anywhere from 5 to 20 turns to learn. Continue to play the game as normal until the required amount of turns have passed.
Open the technology tree and select "Animal Husbandry." Once this technology has finished, all available animals are shown on your map. Due to the random nature of "Civilization IV," horses appear in a random spot each game.
Build a new city next to the horses if they are out of the range of your current cities.
Select a worker. Click on the horses and select "Pasture" to have your worker build a pasture on top of the horses.
Connect the pasture to your city with roads once the pasture has been built. This supplies the nearest town with horses.
Connect all of your cities together with roads to supply horses to your entire civilization, opening up new units and technologies such as horseback archers.
If a rival civilization claims horses before you do, you must trade with them to gain access to horses.
