Answer

**Step-by-Step Solution:**

1. **Understanding the Three Kingdom Classification**: The three kingdom classification system was proposed by Ernst Haeckel. It expanded upon the earlier two kingdom classification by adding a third kingdom.

2. **Identifying the Three Kingdoms**: In Haeckel's classification, the three kingdoms included:
- Kingdom Plantae (plants)
- Kingdom Animalia (animals)
- Kingdom Fungi (fungi)

3. **Determining the Third Kingdom**: The question specifically asks for the third kingdom included in this classification. Since Haeckel introduced the kingdom of fungi as the third kingdom alongside plants and animals, it is clear that fungi is the answer.

4. **Conclusion**: Therefore, the third kingdom included in the three kingdom classification is the Kingdom Fungi.

**Final Answer**: The third kingdom included in the three kingdom classification was Fungi.
