In this class we study the complex history of the Mourner's Kaddish (Kaddish Yatom) and we explore how the Kaddish became associated with burial, death, the deceased and mourners.

In this class we study the ancient history of Kaddish, and we explore the earliest sources for this doxology as well as its development up until the Middle Ages.

In this class we continue studying the Korbanot section of the Siddur, with a focus on the later additions to the section and their nebulous medieval origins.

In this class we introduce the section of the liturgy that contains recitations of passages related to Korbanot. We study why and how this practice of recitation began, the motivations behind it and the evolution of it as a ritual.

In this shiur we discuss the Beracha within the Le'Olam prayer "HaMekadesh Et Shimo Berabim". We look out how it evolved into a Beracha used to die "Al Kiddush Hashem" i.e. for the sake of martyrdom.

In this class we discuss the custom of saying the Torah portion of the Akeidat Yitzchak (the binding of Isaac) before Shacharit. We also discuss the prayer said before and after the portion, which is sourced from the Rosh Hashana prayers.

In this class we explore the origins of the Selichot prayers, and we trace the enormously complex layers of development that brought the modern collections into existence.

In this class we examine the many (optional) morning additions that appeared in the Siddurim of the Modern era, such as Adon Olam and Yigdal. We trace some to medieval times and others to more recent developments.
