People can vote on big rules. This is called a referendum. 
Sometimes the vote must be held. This is a mandatory vote. It can be for new rules.

Voting helps people share their views. It lets everyone have a say. It is a way to help lead.
A referendum is a direct vote. It lets people vote on a law or a big idea. This is different from picking a leader to vote for you. 
Some votes are mandatory. This means the law says the vote must happen. This often happens when a country wants to change its constitution. A constitution is a set of main rules for a nation. 
Other votes are optional. These happen when someone asks for a vote. Sometimes the government asks. Other times, the people ask by collecting signatures. A recall vote is one kind. This lets people vote to remove a leader early.
Most votes give a simple choice. You can say yes or no. But some votes have many choices. In 1977, Australia had a vote for a new song. Voters could pick from four different options.
Switzerland has held almost 600 national votes since 1848. These votes help people share their views on important matters.
A referendum is a special kind of direct vote. In most elections, people choose a leader to make decisions for them. This is called representative democracy. In a referendum, the people vote directly on a specific law or idea. This is known as direct democracy. Some referendums are binding, which means the result must be followed. Others are advisory, which means they act like a large opinion poll. 
There are different ways these votes can happen. Some are mandatory, meaning the law requires them. For example, many places must hold a vote to change a constitution. A constitution is the set of main rules for a country. Some votes are also required for big spending or joining international groups. In Switzerland, a mandatory vote happened in 1986 regarding the United Nations. 
Other votes are optional and happen only when someone asks for them. The government might ask for a vote, or the citizens might ask. Citizens can often start a vote by collecting many signatures. This is called a popular initiative. There are also recall referendums. These allow people to vote to remove an elected official from their job early.
Most referendums offer a simple choice between "yes" and "no." However, some allow for more options. These are sometimes called preferendums. In 1977, Australia held a vote to choose a new national anthem. Voters had four different choices to pick from. In 1992, New Zealand held a vote with five different options. 
History shows that these votes have been used for a long time. The word "referendum" comes from Latin. It means "to carry back" to the people. This type of voting may have started in Graubünden, Switzerland, in the 1500s. Since 1848, Switzerland has held almost 600 national votes. Italy has also held many, with 78 national referendums recorded. 
A referendum is a direct vote by an electorate on a specific proposal, law, or political issue. In most modern systems, citizens use representative democracy to choose leaders who then make decisions. A referendum shifts this power toward direct democracy by allowing the people to vote on the issue itself. These votes can be binding or consultative. A binding referendum results in the official adoption of a new policy. A consultative referendum, also called an advisory referendum, functions like a large-scale opinion poll to gauge public sentiment. 
The term "referendum" has deep roots in the Latin language. It is the gerundive form of the verb *referre*, which means "to carry back." In a legal context, it describes a proposal that must be carried back to the people. This is similar to other English words like "agenda," which means matters that must be driven forward. Some people use the term "plebiscite" interchangeably with referendum. This word comes from the Latin *plebiscita*, referring to decrees from the Roman Republic's popular assembly. However, some countries use these terms differently. In Australia, a referendum often concerns the federal constitution, while a plebiscite might not. 
Referendums can be classified by how they are initiated and their legal requirements. One major category is the mandatory referendum. These are legally required if certain conditions are met. For example, many nations require a mandatory vote to ratify constitutional changes or international treaties. In Switzerland, mandatory referendums are used for joining supranational communities. This occurred once in 1986 during a failed attempt to join the United Nations. Other mandatory votes include financial referendums. In California, the state government cannot borrow more than $300,000 without a public vote on a bond proposition.
Another category is the optional referendum, which happens only when requested. These can be initiated by the executive branch or the legislature. They can also be "bottom-up" processes started by citizens. A popular initiative is a citizen-led process to propose new laws. Conversely, a popular referendum allows citizens to oppose or strike down existing laws. There is also a specific type called a recall referendum. This allows the electorate to remove an elected official from their office before their term ends. This can apply to a single legislator or an entire legislative body.
While many referendums offer a simple "yes" or "no" choice, some use more complex methods. These are sometimes called "preferendums" when voters can weight their support. Multiple-choice referendums allow for several different options. Sweden held multiple-choice referendums in 1957 and 1980. In 1977, Australia held a referendum to choose a new national anthem, offering four choices. New Zealand used five options for an electoral system vote in 1992. Guam even used six options plus a blank option in 1982. These votes often use systems like instant-runoff voting to determine a winner when no single option gets an absolute majority.
History shows that the use of referendums has changed over time. The practice is thought to have originated in the Swiss canton of Graubünden as early as the 16th century. After a decline in the mid-twentieth century, referendums became more popular after the 1970s. This shift happened because people began to focus more on specific policy issues rather than just political parties. Switzerland has been a major user of this tool. Since its inauguration as a modern state in 1848, Switzerland has held almost 600 national votes. Italy also ranks highly, with 78 national referendums recorded. 
Referendums serve as a vital link between the government and the governed. They are often used selectively for major shifts, such as changing voting systems. Because they involve direct decision-making, they allow the public to act on issues where officials might lack the desire to change. Whether they are used for civil rights, finance, or independence, they remain a powerful mechanism for political expression. They allow the complexities of a society to be voiced through a single, direct action.
