**Step-by-Step Solution:**

1. **Understanding the Classification System**: The question asks about the classification system proposed by Linnaeus. It is important to know that Linnaeus is known for his work in taxonomy, which is the science of naming, describing, and classifying organisms.

2. **Historical Context**: Before 1969, organisms were primarily classified into two main groups: plants and animals. This classification was based on certain characteristics, such as the presence or absence of a cell wall.

3. **Linnaeus's Contribution**: Linnaeus, often referred to as the "father of taxonomy," introduced a classification system that divided living organisms into two kingdoms: Plantae (plants) and Animalia (animals).

4. **Basis of Classification**: The classification proposed by Linnaeus was primarily based on the presence of a cell wall in plants and its absence in animals. This fundamental distinction was the basis for his two-kingdom classification system.

5. **Conclusion**: Therefore, the classification system proposed by Linnaeus was a **two-kingdom system** of classification.

**Final Answer**: The classification system proposed by Linnaeus was a **two-kingdom system** of classification.
