On account of, because of, as in Thanks to your help, we'll be done on time. This phrase alludes to gratitude being due to someone or something. It is also put negatively, no thanks to, meaning “without the benefit of help from,” as in We finally found your house, no thanks to the confusing map you drew. This usage, first recorded in 1633, is about a hundred years older than the first term, recorded only in 1737.
