Some people want to go back in time. 
Long ago, a big change happened in France. This was the French Revolution. Many people wanted new rules. But reactionaries wanted the old kings back. 
They also wanted the old church to have power. They liked the old ways of life. They did not want things to change.
Later, many more changes happened in Europe. People fought for new ideas. Reactionaries tried to stop these changes. They wanted to keep things the same.
Today, people use this word in many ways. It can be a mean word. It can also just describe an idea. It is a way to talk about the past.
A reactionary is a person who wants to go back in time. They believe society was better in the past. They want to bring back old rules and ways of life. 
The word comes from the French Revolution. During that time, many people wanted big changes. But reactionaries wanted to restore the old kings and the Church. They wanted the power of the past to return. One group in France was called the legitimists. They wanted the House of Bourbon to rule again.
In the 1800s, leaders tried to stop new ideas from spreading. Prince Metternich of Austria worked to keep things stable. He used alliances to stop revolutions in Europe. 
In the 1900s, the word was used in new ways. Some groups used it as a mean label for their enemies. For example, people in the Soviet Union used it against others. Even leaders like Joseph Stalin used old, strict rules. Some people also used the word to describe leaders who did not like new freedoms. 
A reactionary is a person who wants to return to a previous state of society. They believe the past had good qualities that are missing today. In politics, this idea is part of the right-wing side of the spectrum. While conservatives want to keep things as they are, reactionaries want to undo recent changes. They seek to restore a former way of life. Some people use this word as a mean label or a slur. Others, like the historian John Lukacs, have used it to describe their own views. 
This idea grew from the French Revolution in the late 1700s. The word comes from the French word for "reaction." During this time, many people wanted to bring back the power of kings and the Church. One group in France was called the legitimists because they supported the House of Bourbon. In the 1800s, reactionaries often looked back to the era before the Industrial Revolution. They liked the old ways of feudalism and traditional social orders. They wanted to bring back the authority of the Church and the State. 
History shows many moments where these groups tried to change things back. After the rule of Maximilien Robespierre ended in 1794, a movement called the Thermidorian Reaction took place. This group tried to find a middle path after a very violent time. Later, after Napoleon fell, the Bourbon Restoration brought back a monarchy in France. King Louis XVIII ruled during this period. He dealt with a group of very strict royalists called the Ultras. This group wanted to return society to the ways of the past. 
Leaders also worked to stop new political ideas from spreading across Europe. Prince Metternich was the foreign minister of the Austrian Empire from 1815 to 1848. He helped create the Concert of Europe to keep things stable. He worked with the Holy Alliance, which included Russia, Prussia, and Austria. This alliance was meant to protect monarchs against new revolutions. Metternich used the Church as an ally to help maintain order. Even so, many revolutions still shook Europe in the year 1848. 
In the 20th century, the word was used in many different ways. People in the Soviet Union used it to label their enemies during the Russian Civil War. Some used it to describe leaders who supported strict or authoritarian rules. For example, the term was linked to regimes in Spain and Portugal. Even Benito Mussolini and the Italian Fascists talked about it. They claimed that fascism was a form of reaction. However, they also argued that their movement was actually a new and revolutionary creation. 
A reactionary is a person who favors returning to a previous state of society. They believe the past possessed positive qualities that are missing in the present. In politics, this idea sits on the right-wing side of the spectrum. While conservatives seek to preserve the current socio-economic structure, reactionaries want to undo recent changes. They aim to restore a status quo ante, which is a previous state of affairs. This stance opposes the social transformation of society. Some people use the term as a negative label or a political slur. However, some writers and historians have adopted the term to describe their own views.
The term originated during the French Revolution in the late 18th century. It derives from the French word for "reaction." This period created three important political descriptors: "reactionary," "conservative," and "right." In its original French usage, it meant a movement toward reversing an existing state. The first English usage appeared in 1799 in a translation regarding the Coup of 18 Fructidor. During the 19th century, reactionaries often idealized the pre-modern era. They looked back to the time before the Industrial Revolution and the French Revolution. They often supported feudalism and traditional social hierarchies.
One important moment was the Thermidorian Reaction in 1794. This movement occurred within the French Revolution to oppose the Jacobins. The Jacobins were a radical group led by Maximilien Robespierre. After Robespierre was overthrown on 27 July 1794, the French National Convention regained power. The Thermidorian Reaction stopped the frequent use of the guillotine. It sought a middle course between radical revolutionaries and monarchists. This period led to a time of relative exuberance and corruption in France.
Following the fall of Napoleon, France experienced the Bourbon Restoration. This movement reinstated the Bourbon dynasty as a constitutional monarchy. King Louis XVIII ruled during this time with an elected lower house of parliament. He faced a group of strict royalists known as the Ultras. This group was so dedicated to old ways that they were called the "chambre introuvable," or "unfindable house." These Ultras sought to revert laws to the time of absolute monarchy. They wanted to return society to the era of Louis XIV. 
In the 19th century, leaders worked to contain revolutionary forces across Europe. Prince Metternich was the foreign minister of the Austrian Empire from 1815 to 1848. He was a key figure at the Congress of Vienna. He helped establish the Concert of Europe to maintain order after Napoleon's defeat. Metternich worked with the Holy Alliance, which included Russia, Prussia, and Austria. This alliance acted as a form of collective security against revolution. Metternich used the Catholic Church as a principal ally to promote stability. Despite these efforts, many revolutions still broke out across Europe in 1848. 
The 20th century brought new and complex uses for the word. In the Soviet Union, proponents of communism used "reactionary" as a pejorative label. They used it to describe enemies like the White Armies during the Russian Civil War. In Marxist theory, the term describes people whose ideas might contain elements of feudalism or capitalism. The label was also used by non-socialists to describe various political groups. For example, a British diplomat used it to describe the Chinese Royalist Party in 1912. 
Reactionary politics also appeared in different forms within left-wing governments. In the Soviet Union, Joseph Stalin implemented conservative social policies. These included restrictions on abortion and the re-criminalization of homosexuality. The term is also used to describe supporters of authoritarian regimes. Examples include the governments of Vichy France, Spain under Franco, and Portugal under Salazar. Even the Italian Fascists addressed the term. Benito Mussolini once stated that "fascism is reaction." However, his movement also claimed to be a revolutionary and original creation. They argued that their state was not a return to monarchical absolutism.
