Well, just like the Arabic numbers the roman numerals also have their point of origin which brings the onset of this system of numbers. As we already know roman numbers use Latin letters to form the numerals, unlike Arabic numbers. These Latin letters are the I, V, X, L, C, D, and M in their respective manner to form the roman numerals. All these letters either can be used individually or in the combination with one another to form the roman numerals. So as it is visible here that the Latin letter "I" is the first letter that is used as the first roman numeral.
One can use this letter to simply write the number one individually and also use the number one to make the other number in the roman style. For instance, you can write the number eleven in the roman numerals as XI which shows the visible use of the letter I. This is how all the roman numerals happen and how the first Latin letter I play its role to denote the number 1 in roman format. We thus hope that this detailed guide will provide you with enough understanding as to how one should write the 1 in roman style.
Well, to write the 1 in roman numerals you first need to understand how this Roman numeral takes its whole formation. You can simply understand it by putting shifting your focus to the Latin letters from where the roman numerals hold their origin. Here the Latin letter "I" is the one which is used to denote the roman numeral 1 as the very first roman number. Just like the Arabic numbers the roman numeral I has its utmost significance.

Similarly, the application of this numeral 1 just goes on further for the roman numerals with its core role. So we do hope that it would be easier for you now to write the 1 in roman style with a well conceptual understanding of this numeral.
