Lesson 1: California Becomes a U.S. Territory

In this Grade 4 lesson from California myWorld Interactive, students learn how American, Russian, and other settlers came to California during Mexican rule and how trailblazers like Jedediah Smith and John Bidwell opened overland routes using wagon trains. Students explore key vocabulary including immigrate, trailblazer, and wagon train while examining why settlers moved to California for economic reasons such as farming and fur trading. The lesson is part of Chapter 4: The Gold Rush and Statehood, building toward understanding how California eventually became a U.S. territory.

Section 1

Early Settlers in Mexican California

Key Idea

In the early 1800s, California was part of Mexico. It was a quiet land with few people, but other countries saw its rich resources.

Russian traders came to hunt for valuable furs along the coast.

Section 2

Trailblazers Open the Way to California

Key Idea

Getting to California by land was very difficult because there were no roads across the huge mountains and deserts.

Brave explorers called trailblazers had to find a way through.

Section 3

Settlers Journey to California

Key Idea

Getting to California was a long and hard journey for early American settlers. People traveled in two main ways: by land in covered wagons or by sea on large ships.

Many pioneers traveled in wagon trains on overland routes like the California Trail. The trip took many months, and families faced huge mountains, hot deserts, and shortages of food.

Section 4

Americans Revolt in California

Key Idea

Many Americans believed in Manifest Destiny, the idea that the United States was meant to stretch all the way to the Pacific Ocean. This created tension with Mexico.

In 1846, a group of American settlers in Sonoma started the Bear Flag Revolt. They captured the town, raised a new flag with a bear on it, and declared California an independent republic.
