Long ago, some people had bad ideas. 
People thought they could make humans better. They tried to pick which families had children. This was very unfair to many people.
Some leaders used these ideas to be mean. They treated many people very badly. This caused a lot of sadness.
Many people worked hard to stop this. They said all people are born equal. We must be kind to everyone.
Today, doctors use science to help families. They let parents make their own choices. It is good to respect everyone.
Eugenics is a set of ideas about human traits. 

There were two main ways people practiced eugenics. Positive eugenics tried to help people with "good" traits have more children. Negative eugenics tried to stop others from having children. This was often done through forced medical steps like sterilization. 
Many people spoke out against these ideas. They argued that all humans are born equal. Today, science is used differently. Doctors help families with genetic testing. Now, the focus is on helping parents make their own choices.
Eugenics is a set of ideas about how to change human traits. 

There were two main ways that people practiced eugenics. The first way was called positive eugenics. This aimed to help people with "good" traits have more children. These traits might include being healthy or successful. 
History shows that these ideas have been around for a long time. 
By the early 1900s, eugenics became a very large movement. 
Not everyone agreed with these ideas from the start. 
Eugenics is a set of beliefs and practices designed to change the genetic quality of a human population. 
To understand how eugenics works, it is helpful to look at its two main methods. The first is called positive eugenics. This method aims to increase the number of people with traits considered "superior" or "fit." These traits might include intelligence, health, or social success. Proponents of positive eugenics suggest using tools like financial incentives or even advanced technology like in vitro fertilisation. 
These two methods can be applied in coercive ways, meaning people are forced to comply. In Nazi Germany, for example, the state made abortion illegal for women it deemed genetically superior. Negative eugenics has historically included forced sterilisation and forced abortions. These practices were used to target people based on physical, mental, or perceived moral qualities. Such actions were often used to control specific groups of people. This demonstrates how eugenics can shift from a social philosophy into a tool of state control.
Ideas similar to eugenics appear in ancient history, though the evidence is often debated. 
The modern academic study of eugenics began in the late 19th century. 

By the early 20th century, eugenics had become a massive global movement. It was supported by many governments, universities, and even religious leaders. 
Not everyone supported the rise of eugenics. Several thinkers and scientists argued against it from the beginning.
