Introduction 1  (bringing into use/to a place) /ˌɪntrəˈdʌkʃn/

The act of bringing something new into being, for the first time, or bringing something to a new location. In this context, "introducing" often refers to the introduction of a new idea, product, process, or culture. It can refer to the introduction of an innovation or a new method in manufacturing (the introduction of new manufacturing methods), or the establishment of a new institution or law (the introduction of compulsory military service). The term "introducer," when used as a person's name, implies someone who has introduced something new or brought it into existence. For example:

- The introduction of new manufacturing methods revolutionized the industry.

- The author of the book is an introducer, known for introducing many novel plants to the British flower garden.

- Companies that are introducing new technologies are often at the forefront of innovation.

In addition to these more general uses, the word "introduce" also has a specific connotation related to history and culture. For example, when used to refer to the introduction of Christianity in Russia:

- The 1,000th anniversary of the introduction of Christianity to Russia is a significant occasion.

When writing about such occasions, you might also use other terms such as "religion" or "church" depending on whether you are referring to the religion of Christianity itself, its spread throughout Europe, or its impact on Russian societal development.
