During its long history, alcohol has caused (and "solved") a myriad of problems. There's no dispute that excessive consumption has caused damage to countless lives and society in general. Controlling its use has been a problem since the beginning of civilization. The solution of the Dry Crusader is one of complete prohibition.
The Dry Crusader is what you get when you cross The Teetotaler with the Moral Guardians, the Principles Zealot, and (sometimes) the Well-Intentioned Extremist tropes. It's a character who believes the consumption of alcohol is always evil in any amount at all times to everyone. Anyone who's unfortunate enough to be drinking a glass of beer within the Dry Crusader's line of sight will soon be subjected to an angry harangue warning him of the spiritual, moral, and health hazards that will result with one sip of the demon rum. It goes without saying that nothing short of a total ban on alcohol will satisfy the Dry Crusader. To achieve this goal, this person on occasion is not above resorting to any means necessary.
When the Dry Crusader appears, it's often in works that are set in the United States during the 19th and early 20th century which is the time the Women's Christian Temperance Union and the Anti-Saloon League were at their peak of influence, and which ultimately led to the Prohibition era, which lasted from 1920 to 1933 and saw the rise of organized crime to meet the demand. Instances of the Dry Crusader in stories set after the repeal of Prohibition in the U.S. in 1933 are far less common. You'll still come across characters who inveigh against all consumption of alcohol but, recognizing its historic total failure, they're less likely to advocate a complete ban or subjecting bars and taverns to hatchetization to achieve their goal.
Often the character will serve as a Strawman Political and usually be Played for Laughs. Expect your crusader to unknowingly imbibe alcohol at some point (sometimes an honest accident, sometimes for a prank, sometimes medicinally) and for them to get hilariously soused after one drink. This may break some of their pride and help them admit that they're only human, and to be a bit more understanding towards occasional indulgence. Or it could just make them angrier — tricking someone into imbibing a substance they have a moral revulsion to is generally not a nice thing.
The Dry Crusader is not limited to the U.S. and can also be found in stories set in Canada, Britain, and other countries that have a history of puritanism and campaigns against the consumption of alcohol.
In many ways, the Smug Straight Edge is the descendant of the Dry Crusader in that both have a tendency to act self-righteously toward and condemn those who imbibe.

- In the DC Comics Elseworld Batman: The Blue, the Gray, and the Bat, two Dry Crusaders are on the same coach as Bruce Wayne as he heads out West. They turn out to be the Big Bads behind the whole thing.
- Lucky Luke: Thanks to taking place during the Old West, these characters pop up every now and then, usually temperance groups consisting mostly of women, but men too, such as the visiting scientists from The Black Hills, who not only order things like tea or lemonade in a saloon they stop at with Luke, they also give a lecture about the health effects on alcohol to an Indian they meet. An interesting example is Big Bad August Oyster from Calamity Jane, who starts out as a saloon owner using his business to smuggle guns, but after losing it in a bet, he lies to the local temperance group that he's decided to turn over a new leaf and become this trope, so they'll help him shut it down.
- In The African Queen, Methodist missionary Rose Sayer (Katharine Hepburn) is visibly upset when her captain Charlie Allnut (Humphrey Bogart) starting drinking gin, but she politely keeps her opinions to himself. After he gets drunk and starts ranting at her, however, she dumps all of his gin out while he's sleeping it off.
- Cora Massingale, leader of the Women's Temperance League, in The Hallelujah Trail.

- In the Harold Lloyd comedy Hot Water, the main character's obnoxious mother-in-law turns out to be one, which does not bode well for his attempt to use Liquid Courage to stand up to her.
- A man is enjoying a drink at a bar, when a nun comes in, decrying the evils of drink. He sighs, puts down his drink, and asks her, "Have you ever had a drink, Sister?" The nun admits she hasn't. "Well then, how do you know it's evil?" "My Mother Superior told me so," she replied. "Tell you what," says the man at the bar. "I'll buy you a drink. If you don't like it, I'll swear off alcohol for life. But if you do like it, you'll never bother anyone in this bar again." "I can't do that!" replied the nun. "I'm a nun! What would people think if they saw me drinking?!" "I'll just have the bartender put the drink in a teacup. Then no one has to know." The nun agrees, and he goes up to the bar. He orders another whiskey sour for himself, and a vodka on the rocks. He lowers his voice and asks for the vodka to be placed in a teacup. The bartender says, "Oh, no, not that nun again!"
- In both the book and movie version of Elmer Gantry, the title character publicly preaches against the evils of booze. Privately, it's another story. (In the novel, he does eventually quit.)

- Dry Crusaders appear in Victoria II in several forms, such as events asking the leader to teach temperance, sometimes even asking to outright ban alcohol over the nation. The player themselves can in turn become one, but this does come with some risks such as encouraging reactionary thought or encouraging general population militancy, which may not end well.
- In The Elder Scrolls III: Morrowind, the priest at Fort Frostmoth (Antonius Nuncius) in the Bloodmoon expansion plays with the trope. He claims to be intercepting and hiding the alcohol shipments to the fort for moral reasons. In actuality, he's hoping that the disgruntled soldiers will rebel so that he can be reassigned someplace more hospitable than Solstheim.
- In Guns, Gore & Cannoli, the Bureau of Prohibition, having realized that Prohibition was a failure, created a poison so they could spike the ingredients of alcohol. It was rejected because the effects were too..."extravagant."

At the end of the episode, it's discovered that the prohibition law was repealed only a year after the original ban, and everything returns to normal.
- Carrie Nation.
Back in 1880, Kansas residents had voted for prohibition, but the law was largely ignored by saloonkeepers. They operated openly, but Nation would change all that. First she prayed in front of an establishment in 1890. She struck at her first saloon on June 1, 1900. Initially, she used rocks, bricks, and other objects for these attacks, then turned to the hatchet. Nearly six feet tall and strapping, the determined woman closed the saloons in Medicine Lodge.Nation responded with alacrity to appeals from citizens of other towns to close their saloons. She entered states where liquor sales were legal. Her behavior provoked a tremendous uproar and sent her to jail repeatedly for disorderly conduct and disturbing the peace. (FYI: Carrie Nation)
- Thomas Riley Marshall, who eventually became Woodrow Wilson's vice president, was an active campaigner against liquor. In his case, it stemmed from being a recovering alcoholic himself.
- The early 20th-century evangelist Reverend Billy Sunday frequently preached against drinking alcohol and advocated its abolition.
- Wayne Wheeler of the Anti-Saloon League. His efforts played a large role in the passage of Prohibition in the U.S.
- Many early feminists, including Susan B. Anthony and Elizabeth Cady Stanton, were big supporters of the temperance movement. In fact, a recurring theme in temperance propaganda holds that a seemingly good man becomes a drunkard, leading him and his family into poverty and frequently resulting in, on the man's part, Parental Neglect at best and Domestic Abuse at worst. Today, it is known that alcohol abuse can lead many people to become more uninhibited, although it's certainly not the only cause of violence, domestic and otherwise.
