MCMLXVI
1,966 in Roman numerals is MCMLXVI.

Roman numerals use seven basic symbols: I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000. The general rule is: reading left to right, values in descending order add up. When a smaller symbol comes before a larger one, it subtracts (e.g., IV = 4), which happens in this case.

Step-by-step conversion of 1,966:

1. M = 1,000 → represents thousands.

2. CM = 1000 - 100 = 900 → subtraction rule used.

3. L = 50 → represents tens.

4. X = 10 → represents tens.

5. V = 5 → represents units.

6. I = 1 → represents units.

So, 1,000 + 900 + 50 + 10 + 5 + 1 = 1,966, or MCMLXVI in Roman numeral form.
