The Industrial Revolution dramatically transformed American society, the economy, and labor relations in the late 19th century (roughly 1870–1900), a period often called the **Gilded Age**. These changes reshaped the United States into a modern industrial power.

## 1. Economic Transformation

### 🔹 Rise of Big Business
- The U.S. shifted from an **agrarian (farm-based) economy** to an **industrial economy**.
- Massive growth in industries like **steel (Andrew Carnegie), oil (John D. Rockefeller), railroads, and manufacturing**.
- Development of **corporations**, trusts, and monopolies.
- Introduction of new business practices:
  - Vertical integration (Carnegie)
  - Horizontal integration (Rockefeller)

This led to:
- Rapid economic growth
- Increased national wealth
- The U.S. becoming a leading global industrial power

However, wealth became **highly concentrated** in the hands of a few industrialists, creating major income inequality.

## 2. Social Transformation

### 🔹 Urbanization
- Millions moved from rural areas to cities for factory jobs.
- Cities like New York, Chicago, and Pittsburgh grew rapidly.
- Overcrowded tenements, poor sanitation, and unsafe living conditions became common.

### 🔹 Immigration
- “New immigrants” from Southern and Eastern Europe arrived in large numbers.
- Immigrants supplied cheap labor for factories.
- Cultural diversity increased, but so did nativism and discrimination.

### 🔹 Growth of a New Social Structure
- Emergence of:
  - Industrial elites (“robber barons” or “captains of industry”)
  - Expanding middle class (managers, clerks, professionals)
  - Large urban working class

This widened the gap between rich and poor, contributing to social tensions.

## 3. Changes in Labor and Working Conditions

### 🔹 Factory Work
- Shift from skilled artisanal labor to **unskilled wage labor**.
- Long hours (10–12 hours per day, 6 days a week).
- Low wages.
- Dangerous working conditions.
- Child labor was common.

Workers had little job security and few legal protections.

## 4. Rise of Labor Unions and Labor Conflict

As conditions worsened, workers organized:

### 🔹 Labor Unions
- **Knights of Labor** (1869): Inclusive, sought broad reforms.
- **American Federation of Labor (AFL)** (Samuel Gompers): Focused on skilled workers and practical gains (higher wages, shorter hours).

### 🔹 Major Strikes and Conflicts
- Great Railroad Strike (1877)
- Haymarket Affair (1886)
- Homestead Strike (1892)
- Pullman Strike (1894)

These events showed:
- Deep tensions between workers and employers.
- Government often sided with business owners.
- Growing fear of socialism and anarchism.

---

## 5. Government’s Role

- Initially followed **laissez-faire** policies (minimal regulation of business).
- Courts often ruled against unions.
- The Sherman Antitrust Act (1890) attempted to limit monopolies but was weakly enforced at first.

Government generally supported industrial growth over labor rights during this period.
